Agreed with the receipts! Here?s a different story, but still on the topic of ATMs and Spanish banks…
I have a Santander, and in the beginning, I didn?t know withdrawing from non-Telebanco ATMs like ServiRed would mean fees, so when I got to that screen saying would you like to go ahead and we?ll charge you something like 3?, I cancelled and didn?t take any money to avoid the fee and went off to look for a Telebanco. The bank still charged me and took me 3 months to get the fees back!!! My bank then told me if it weren?t for the receipts, they wouldn?t refund anything. The duffer I was, I did that twice. What was that saying? Do it once, shame on you, do it twice, shame on me!
Lesson learned - use the right ATM in the first place to avoid problems (where possible… I know it?s a pain) and always keep receipts til the end of the month. The little miss prudence I am, I keep it for 2 months.
