No service after being promised reconnection withi

My DSTV subscription has been suspended even though I am a paid up customer who pays by debit order. When I called the Call centre I was asked for my decoder serial no as apparently that was the cause of the disconnection as they had no serial of my decoder on record. After I have supp**** them with the serial no, I was promised reconnection within 15 minutes. After an hour I called again, spend 20 mins with Lerato on the phone providing her with all the info, including the serial number yet again. Now after 2 hours I have still not been reconnected. When I tried the self service online I get an error message that my smart card is allocated to someone else! Although they have my contact detail they do not come back to me. I even sent an email, which they also ignore.<br>
