Happened to me a few months back, took me over my overdraft limit and my bank just let it happen all they did was send me a letter saying I had exceeded my overdraft and charged me for it.
Next I was waiting for forms I had to fill in and return, it was a couple off weeks before they recredited my account, soon as they did two small amounts vanished as if somebody was testing. This time I made them change my Debit card.
Hope they sort you out quicker than they did me as it certainly caused a few problems being overdrawn for a couple off weeks
