getting bills after cancellation

My name is Rafia De Gama. I used to have a adsl line and a landline ***.<br> <br> I cancelled my service in July by going to the Hatfield branch in Pretoria and filling in the required form. I reconfirmed the cancellation after I received a bill in August at the Menlyn branch,also in Pretoria. I was told the cancellation shows and I will be reimbursed. However to my dismay I have been billed and debited for September too.<br> <br> I am overseas, I have relocated and will not be returning. I have given proper notice and am dismayed at the state fo affairs
