Absolutely. You may have started me off on one of my rants, Justin. Perhaps this should be re-directed to a thread on banking?
If you are not resident in Spain, then you will inevitably have to put yourself at the mercy of the bank to pay your utilities etc. Get registered online and check accounts regularly.
If you live/are going to live here, and if you can afford the time, I strongly suggest that you pay any bills you can yourself. Some companies (telephone, insurance for example) only accept payment by DD, but since the banks can be alarmingly shoddy, it's much safer to avoid this if poss. It can be a nuisance - many banks are actively trying to discourage you paying bills at the counter, because a) it makes work for them and b) the majority of their staff are innumerate and make too many mistakes, which c) makes work for them. My water bill can only be paid at Unicaja on a Tuesday or Thursday, between 8.30 & 10.00am, and only if the queue is short enough to actually reach the counter in an hour & a half! However, I can pay it from my account using the ATM at my bank at any time, no charge, by scanning the bar code and following the on screen instructions (which can be displayed in English). Telefonica would have you believe you have to give them bank details and set up a DD, but this is not true - just tell them "no" and pay in cash. This, along with my electric bill, I can pay at a variety of banks at a variety of hours & days, but at ANY time in the Post Office, which is open 8.00am to 8.00pm. Just watch out for the grumpy old git who ALWAYS short changes you by 1 or 2 cents (think about it, it adds up throughout the day!)
Other potential problems? Submitted my tax return forms to the bank one time, when I was due a rebate. This should have been credited to my account from Hacienda. Unfortunately, the clerk hit the wrong button, and debited my account for the same amount. When I spotted the error, I was told I would have to apply to Hacienda to get my money back! After screaming my t*ts off to the manager, he finally agreed to rectify the problem - by offering me a loan for the amount I was down, until such time as Hacienda repaid the money missing from my account. No interest either - how kind. As for insurance companies - we were unfortunate enough one year to have 3, albeit relatively small, claims on our property insurance. When we received our renewal notice, we were amazed to find our premium had gone up as a result - but by more than the 3 claims put together! We immediately contacted the insurance company and told them they could keep their policy. OK, we should have put it in writing, but we didn't realise that they could simply go ahead and take the money for the next year from our bank account anyway. When we spotted the debit 2 weeks afterwards, we were told by our bank not to worry, because you have 15 days to contest any payments made from your account on your behalf! Just in the nick of time, we got our money back. But what if.....
Glad I got that off my chest. I'm now going into the Alhambra thread to look at Janice's photos and calm down.
