The first time I used my bank debit card in Pamplona in 2013 I mistakenly pressed the button for our joint chequing account at home in Canada. I got the money I asked for but after another withdrawal a few days later I heard back from my husband at home that my withdrawals were coming out of our joint household chequing account. On my next visit to the bank (Santander) I tried to get money out of my savings account but I was unable to change my original setting for "chequing" to "savings." I was also unable to arrange a transfer of funds from my savings to reimburse our household chequing account, so I changed banks and went to Banco de España where I was careful to make sure I pressed "ahorro" for savings, and had no problem. Because we are well known at our small town home branch of our bank where I had had my accounts flagged that I would be in Spain, it was no problem for me to contact my home branch with an e-mail to the right person and arrange for some money to be moved between the accounts. When I returned to Spain in 2015 I used other banks than the one I'd originally used in Pamplona the first time which is a shame because I'd discovered Santander bank in Mexico and liked its high profile and availability and I think it is a very good solid and reliable bank. I think my situation was merely a glitch in the system that can happen when one travels internationally because I unthinkingly pressed "chequing" automatically as I would have if I were at home, and for all I know the glitch could have been remedied by now but I'm reluctant to try it out so I'll stick with other banking institutions for now.
