Homechoice

I had an account with homechoics and I never missed a payment as I made sure I had enough funds on my account, one month they did not take the direct debit and the following month they took double the amount I called them and after being transferred from one department to another I was advised to reverse the money, I contacted the bank and they advised me that they cannot reverse part of the money however they will reverse all of it as it was one payment, I then reversed the money the following month they took triple the amount I reversed it and cancelled the direct debit now my account has been handed over to the credit bureaus I want them to remove all the additional charges and reactivate my account as the fault was on their end in the first place.
