BUREAU INFORMATION NOT UPDATED

i am really disappointed in vodacom. i had 2 contract with them a lap top and cellphone. i have paid up both but on the credit bureau they have not closed my account down and shows im still owing them money. i have sent emails and called them but nothing happend and no one got back to me. why is it that customer service is so bad and thing can not be done timeously.... or is it the fact that there are *********** people workign for vodacom that can not close my account. I DO NOT WANT TO INCUR ANY CHARGES ETC AS THIS WAS CLOSED LONG AGO.
