## Steps, in order

1. **Find the wrong lines on your bill**
   - You have the right to a detailed, clear bill without errors. Charges for services that are not telecoms (for example premium-rate services or a device) must appear separately.

2. **Complain to your operator in writing and get a reference number**
   - Deadline: Within one month from when you learned of the problem; complaining to the operator in that time is required before you can go to the OAUT.
   - Say which lines are wrong, the amount, and ask for a corrected bill and a refund. Use the channel you used to sign up, or phone: the operator must accept both. It must give you a reference number for your complaint. If you complain by phone, ask for a document that proves you filed it and what it said.

3. **If there is no answer within a month, or you disagree, complain to the OAUT**
   - Deadline: Within three months from the operator's answer, or from the end of its one-month period to answer.
   - The Oficina de Atención al Usuario de Telecomunicaciones (Ministry) handles complaints from individuals, self-employed people and microenterprises. File online (with a digital certificate) or on paper, and attach the operator's reference number, bills and contract. Billing disputes are one of the matters it resolves. It has six months to decide, and the operator must comply with its decision.

4. **Instead of the OAUT: consumer arbitration, if your operator accepts it**
   - Deadline: To keep the OAUT open, ask for arbitration within the same three months.
   - You can take the dispute to a Junta Arbitral de Consumo; it only works if the operator submits to it. If the operator refuses arbitration, your three months to go to the OAUT count again from that refusal.

5. **Last resort: court**
   - Before suing you must have tried to negotiate, and you need written proof of that attempt: for example, proof that the company received your request to negotiate or your proposal. If it does not reply within 30 calendar days of receiving it, the attempt counts as ended without agreement.

- You can ask to block international calls and premium-rate numbers. The operator must do it within 10 days; if it does not, the cost of those services is on the operator. (https://www.boe.es/buscar/act.php?id=BOE-A-2009-8961#a24)

- In its decision the OAUT can cancel bills, order refunds of amounts billed wrongly and take other measures to restore your rights. (https://www.boe.es/buscar/doc.php?id=BOE-A-2007-8274)
- If a consumer arbitration board has started a procedure, you cannot use the OAUT unless the request is closed without a decision on the merits or the parties withdraw from arbitration. (https://www.boe.es/buscar/act.php?id=BOE-A-2022-10757#a7-10)
- In court claims of up to 2,000 euros you can act yourself, without a lawyer or a procurador. (https://www.boe.es/buscar/act.php?id=BOE-A-2000-323#a31)
