Closed account not closed more than 6 months later

I requested, in your Westgate branch on YOUR Westgate phone to cancel the number at my old home and got a reference number. You are still charging me for my old account. I have held on countless times (often for an hour or more) to deal with this and sent emails to you. I have visited branches and waited in queues. I have sms'ed the complaint when you have asked for feedback, all to no avail.<br> <br> Still I am receiving accounts and I moved in October and have a new Telkom number which I opened after the old one was closed down. Foolish of me really, I won't renew it at this rate when the contract ends in 1 1/2 years. <br> I really do not know how to cancel this old contract that in my mind was cancelled at end November !! HELP!!!
