Thing that annoys me is you have little choice.
We had an incident recently where we have two accounts, one for bills and the other for spending.
My wife set up a gym membership and gave them the bill account details, after 5 weeks they had not taken the standing order so she paid the fee by Visa card out of the spending account. After 7 weeks they asked her to sign another standing order as the first one had been lost. Upon checking the accounts on week 9 they had taken £35 from both accounts, putting us £2 overdrawn on the spending account. Phonecalls to the bank and gym were a waste of time and the bank charged us £35 for going overdrawn, hows that fair?
yep thats what happen to me, still waiting for the money bank its been 28 days.
