billing me for i what i dont have

Telkom has been billing me on an business account that i dont have and they handed me over to the attorneys and i have paid them now they are sending me another invoice this is black tax and im not going to pay this amount, because now im told that its a debit order fees which were never explained to me when i opened the account with them, Bad service . i have logged a despute with them and i know they will make stories for me to pay them they are so good in making people look like bad payers and ruining peoples credit records
