BEING FORCED TO PAY FOR A SETTLED ACCOUNT!!!!!

My husband settled his account in November and requested it be closed. He received a bill of around 80 something odd rand and went to branch where a guy helped him, called the call centre where they said they would reverse the charges and close the account. This was not done as he then received a message stating he owes more money, we went through the complaint process again and nothing was done as they are now trying to force him to pay over R300 which is ridiculous. When we asked what this money was for we were told we being billed for magazines, magazines we don't even receive!!! Somebody better do something about this , we are now seeking legal advice. How can nobody be able to complete the simple task of closing an account yet you open one in 5 minutes? If there are any implications on his credit record TGF group you are in trouble. This is unfair treatment!!!!! You need to close this account ASAP.
