Which customer-service personas are available on /practice/customer-service?

Five native Spanish-speaking personas stand by today: a returns specialist greeting you at the store counter, a frustrated customer on the support line, a billing support agent working through an invoice dispute, a technical support rep on a device-diagnostic call, and a store manager stepping in on the floor when the exchange has escalated. Each stays in character through the awkward, the routine, and the consequential — and each parks on a single carefully-chosen phrasing when the moment at the counter matters.

Is the first branch free?

Yes. The returns specialist at the counter is free to start — you run the first branch without a paywall and the transcript is yours. The full branching tree on the frustrated customer, billing support agent, technical support rep, and store manager unlocks on Pro; if you start one on a Free plan, you get a 24-hour preview window so you can feel the next branch before deciding to upgrade.

How does the branching dialogue work in practice?

Each persona adapts to what you actually say. Tap a choice from the beat the persona offers, the persona replies in character, and the next beat appears with three or four fresh options — right there on the page. Difficulty is shown per persona (A2 frustrated customer → B1 returns specialist / billing / tech-support / store manager) so you can rehearse the customer-side complaint before you walk into the agent-side counter.

Practice the customer-service conversationswhere one phrasing changes the outcome.

Table-front, returns counter, support line — the customer-service encounters where a single carefully-chosen phrasing changes the outcome.

You walk into a frontline customer-service room — a returns counter, a complaint line, a billing call where the figures don't add up, a tech-support line where the box won't connect, or the floor where the manager steps in. Pick the moment you need to rehearse today.

Why GlobalLingo, not generic tutoring

The conversation is the curriculum.

Every other app teaches you 100 languages. We teach the five everyday customer-service conversations that matter — the returns counter where the defect has to come across, the complaint line where frustration has to be acknowledged, the billing call where the disputed figure has to land, the tech-support line where the diagnostic walks to a fix, and the manager who steps in when the line stalls.

Practice the conversation at the counter

Generic tutors drill flashcards. We rehearse the moment: the receipt and the defect you bring to the returns counter, the figure you contest on the billing line, the device model and the symptom you give to tech support, the calm phrasing you use when the manager steps in. The phrase that lands matters more than the grammar you walked in with.

Personas that adapt to your replies

Each of the five personas (returns specialist, frustrated customer, billing support, tech support, store manager) holds the line on register and pacing. The frustrated customer escalates when the agent goes procedural; the billing support agent asks for the invoice number when the figure is vague; the tech support rep runs one diagnostic step at a time; the store manager decides when the exchange stalls. The tree is the curriculum.

four skills, customer-service-shaped

What you’ll learn to say — and what you’ll understand when they say it back.

The same four-skill scaffold that powers every GlobalLingo conversation persona — adapted for frontline customer-service encounters where returns-counter vocabulary, complaint-tone register, billing-vs-technical triage, and manager-style authority all have to line up in the same exchange.

Returns-counter vocabulary

Receipt and product at the devoluciones (ticket de compra, etiqueta, caja original), the category of reason (defecto de fábrica, cambio de talla, arrepentimiento), and the resolution vocabulary (reembolso, vale de seis meses, cambio por otra referencia) — drilled inside a real back-and-forth, not in isolation.

Complaint-tone register

The frustrated-speaking customer uses informal contractions and a fast cadence; the front-of-house voice has to lower the register, mirror back the acknowledgment, and pivot to a concrete next step. A single mis-phrased answer turns a billing dispute into a supervisor call. A single, calmly-chosen phrase resolves it on the line.

Billing vs technical triage

Billing disputes are about figure-and-date confirmation (cargo no reconocido, número de factura, importe exacto, fecha del cargo). Technical support is about model-and-symptom walk-through (modelo del dispositivo, qué ve ahora mismo, cuándo dejó de funcionar). The phrase that fits the moment matters because billing phrasing never fixes a faulty cable.

Manager-style authority at the floor (microscale)

When the returns specialist and the frustrated customer cannot bridge, the manager steps in — calm, authoritative, decisive. Recapping the case in one sentence, acknowledging the wait, and handing the customer a clear next step before they walk out. The persona models how to de-escalate a tense exchange without giving up the floor.

Returns specialist

What the branches feel like

A vague answer restates. A precise one advances.

The persona reads what you say and decides what comes next. Every vague phrasing is a moment to find a more concrete one — every firm, on-tone reply unlocks the next beat.

Billing dispute on the line → cite the figure or loop the call

A thin "No reconozco este cargo" triggers the billing support agent to restate field by field — invoice number, disputed figure, dispute date — until the answer comes back in the register the call needs. The next beat forks: request a one-call credit, escalate to a supervisor for the recurring case, or open a formal dispute for the disputed charge.

Manager steps in → recap, acknowledge, decide

When the returns specialist and the frustrated customer cannot bridge, the manager walks in with calm authority — short recap, an acknowledgement of the wait, a concrete decision the floor can back, and a recap of the next step before the customer walks out. The persona models how to make the call feel resolved without giving the floor.

Keep practicing the vocabulary that came up
