Telkom -breach of contract

I had a 4mb uncapped ADSL deal with Telkom. I then took up the R699 Explora deal with 50Gb on a 10mb line. Problem is. The promised hardware has not yet been delivered but the incident shows closed on the Telkom system. As Telkom and/or anybody acting on their behalf did not honour their side of the contract I now wish to cancel the 10mb deal and revert to my 4mb ADSL package. I tried calling Telkom and was sent from Cancellations to Sales to Cancellations to Sales etc. That was after holding for more than 15minutes. $$xx===$+@!!!.<br> <br> After waiting so long I purchased the Explora from Game. <br> <br> Please place me back on the 4mb line and stop promoting stuff you cannot deliver.
