I started paying R600 a month even though its R549 a month. So after all my reversals done and the extra I pay in I still this sms. I call your call center monthly to sort this out and every month I need to explain when I cancelled the PVR functions and they take forever to search for information and correspondence on your system but call are recorded. My account need to sorted out and every month I NEED TO PAY A RE-CONNECTION FEE FOR YALL INCOMPETENCE PLEASE SORT THIS ISSUE OUT ITS ANNOYING PAYING MONEY FOR WHAT SERVICE.
