Telkom service bad

My contract expired in February and I requested a change from the 'Smart Plan' to 'Prepaid'. I sent the form they requested me to send for the amendment but I never got a response. I have been calling for a follow up , all I am getting is empty promises that my issue has been escalated will be sorted shortly. Till this day they are still debiting from my account even though my contract has expired and I've asked for a change. I am feed up with Telkom's the poor service.

I would NEVER advise anyone to open an account for anything from telkom. NEVER!!!!
