Have a £500 pound overdraft on joint current account. We got a letter about renewing last week so i rang them up and they agreed to renew it and everything appeared fine, we should be able to pay it off in full over the next 3/4 months as I mentioned to them. Checked the account to day and they've taken it off! This means we are now getting unauthorised charges and will be very tight this month as we have a of big bills coming in. I spoke to a very nice lad at the bank today and he's not sure what's happened as it has definitely been approved so he is trying to sort it and make sure the any charges are cancelled, what is the best route to go down here?
