Telkom uncapped landline

I have had a line only with Telkom till 2017/10/31. I changed over to their uncapped line from 2017/11/01. The line included a router with it and after numerous mails on when I would be receiving my router I had no response. So I stopped making payment cause for months on in I have been keeping up on my part of the deal and been paying. Now that I have stopped making payment the line was switched off (which is understandable) but still haven't got a call back. I think the service is seriously pathetic.
