Duplication for my purchases

On the 11/10/2017 I recieved notifications that I made more than 60 purchases effective on the 11/09/2017, these are all purchases ive made during the year and I was billed before so now my account is on a minus 25 670. And I have debit orders that must go off and I cant deposit money as they will deduct it. This is sooo frustrating and messing up my credit record.
