Hey everyone on the forum, the bank has been giving me a major headache recently, so I had to post about it and share my experience with anyone facing a similar issue.
Here’s what happened: last month, while checking my statement, I noticed I was charged twice for a gym membership I had canceled long ago. It was almost €100 in total, and while it’s not a huge amount, I wasn’t just going to let it slide! My bank is Santander, so I went straight to the branch to inquire. It turns out that dealing directly with the bank is much more efficient than going back and forth with the merchant! The money was finally refunded today, so I’ve put together a guide on the whole process to help you all out.

Refund Process Explained
The process isn’t actually that complicated, but the key is to be proactive! Don’t assume the bank will automatically spot the error—you can’t count on that. The whole process can be broken down into these steps for [opening a bank account in Spain]:
Step 1: Gather Evidence
This is the most crucial step! The bank needs you to prove that the charge was unjustified. You’ll need to prepare:
- Bank statement: Highlight the incorrect transaction.
- Supporting documents: In my case, this was a screenshot of the confirmation email for my gym membership cancellation. If it’s a duplicate charge from a merchant, you can provide the POS receipt or electronic receipt for the single purchase.
- Personal identification: Your original NIE/TIE and a photocopy.
Step 2: Go to the Bank or Apply Online
I personally recommend going directly to your bank branch. Face-to-face communication is more efficient, and you can confirm on the spot if all your documents are in order. Just tell the staff you want to “presentar una reclamación por un cargo indebido.” They will give you a form to fill out, and you can give them your evidence to photocopy.
Many banks like BBVA and CaixaBank now also allow you to submit a ‘reclamación’ online through their app or website, usually found under the “Ayuda” (Help) or “Contacto” (Contact) menu. This is a convenient option for those with social anxiety or who don’t have time to visit a branch.
Step 3: Wait Patiently and Follow Up
After submitting your claim, the bank will give you a case number. Be sure to keep this number safe! It’s your reference for tracking the progress. The staff told me the processing time is typically 7 to 15 business days. In my case, I waited about 10 days, and the money was automatically returned to my account. The transaction will appear on your statement as a deposit of the same amount, often with a description like “retrocesión de operación.” If you don’t see any progress after the promised time, you can go to the bank with your case number to follow up.
| Common Processing Stage | Approximate Time | Key Points |
| Submit Claim & Get Case Number | Same Day | Be sure to keep the case number safe |
| Bank’s Internal Review | 5-10 business days | You might receive a call from the bank for verification; see more on [closing a bank account]. |
| Refund Credited | 1-3 business days after approval; learn about [replacing a Spanish bank card]. | Check your bank account and email for notifications |
Claim Rejected | 10-15 business days | If rejected, you will receive a letter explaining why |
In Spain, as long as you have a valid reason and evidence, getting an incorrect charge refunded through your bank is quite reliable. Don’t be afraid of the hassle—it’s your money, so fight for it! I hope my experience helps, and feel free to share your refund stories with different banks! 💪
