Problems with the bank

My Spanish account is blocked which means that I can not put money to the account. I was able to get money from account but not put more money. Because my Spanish account is now empty now I have to get money with my Finnish Visa Electron and I have to pay provision 2e + 2,5% amount of the cash I get. My Spanish bank Santander do not have any idea why the account is blocked and they can not unblock it. They suggested my to delete current account and open new one. Officer also mentioned maybe opening account to another bank. I wonder do they want me to change the bank.
