Yes I have heard terror tales about the BBVA, I bank with them and so did a friend of mine. He moved back to the UK but his house had not sold, but soon after his moved back his house sold. The money went into his Spanish bank account (BBVA) and he asked for it to be transfered to the UK.
The bank manager put all sorts of obstructions in the way so his money stayed where it was. Anyway he asked me to chat to the manager and try to sort things out this end he even gave me power of attorney to do this for him. Still the manager put up a lot of problems so I could not get the money transfered to the UK,.
In the End my friend had to come over and withdraw the money himself, and this took him four days, as the Bank did not hold that amount of cash in the safe.
So be aware of the BBVA..
