The minimum direct debit payment was taken from my bank today and I accidentally bank transferred the full amount borrowed to pay it off. Obviously that would put me the minimum payment over my agreed limit. For example if I owed £100 and the minimum payment was say £30, Tesco took the £30 out of my account and I didn't realise before I bank transferred the full £100 back onto my credit card, say my credit card limit was £1000, this would obviously put me at £1030, what do I do or what will happen?
