Telkom mobile deceptive wrt coverage

Telkom mobile **** about their coverage for IPhone 6 LTE and3G within the randburg area. I signed a 2yr contract based on this map and when my phone signal was very poor, I reported it to them. They sent technicians and said there is nothing they can do, but I must keep paying for a service I was t receiving. I expressed my disappointment and gave an option to retain my phones and only pay once I get signal in the area or I pay for the handsets only and use another provider. They still have not reverted since February and have now blacklisted my phone because I've stopped payments. Below is a copy of the email sent to Marti, the CEO PA of Telkom, on 12 December and again in February: <br> <br> Hi Marti...As mentioned telephonically, I am considering posting this email up to Telkom's FB Page,Sending it to the Times Consumer Editor, HelloPeter.com and other websites to make them aware that Telkom has misled myself as a consumer with incorrect info on the coverage map on which I made my decision to subscribe as well as having deducted money from my account, for services not rendered to the level as per the SLA, altho instructed not to so. <br> <br> I await your reply.<br> <br> Can someone advise or help?
