Ignored Service Cancellation Request

I submitted a service cancellation request to [Email Removed] a week and a half ago and got an automated response saying an agent would call me to confirm within 48 to 72 hours. A week went by with no call. I happen to experience terrible network signal where I live, but I still get missed call SMS's, and during that week I got none. No one tried to call. So, I then visited a Telkom branch at Fourways crossing hoping to sort out the issue there. The guy who helped me told me to submit the cancellation form again and to call 10210 to confirm it myself. I submitted again and actually drove out to find good signal, only to have my airtime run out a few second into finally getting an agent on the line (wait was ridiculous). The \call me back\" online didn't work. I phoned a second time just to be told to send the form yet AGAIN to [Email Removed] I just chatted to and agent online, asking if there's another way I can confirm my request, and she told me there's nothing I can do. I asked her if she could get someone to call me back while I happen to be in an area with good signal and all I got was \"no guarantee\". Please can someone just call me back to confirm?"
