I lived in Spain for four years. When I left, I never closed my account. Recently, I called the bank and they said that I had a negative 5 euro balance, and, to close the account, I needed to contact the branch where I opened it. They told me there were no fees associated with it and that the account was frozen.
A month or two later, I called them and they said that to close the account fully I need to pay maintenance fees and, in total, I owe them 137 euros. Evidently, there were fees. What should I do? Is it possible to pay the five euros and then do nothing?
