Telkom Close Complaint Without Resolving Problem

I raised a problem with Telkom in terms of a 4G internet contract No. *** entered into in July 2015 at R599 per month in an area where only a 3G signal is available. The Telkom reference number for this issue was ***2 dated 17 November 2014, which was closed by Telkom without resolution on 2 December 2015. I called Telkom Customer Service on 18 December 2015 to enquire about cancelling the contract if resolution is impossible. I would pay an admin fee, plus I would be due the remaining instalments of the contract (8xR599=R4792) even though the contract was never met by Telkom (4G promised, 3G delivered). On 18 December 2015 after two interrupted calls, I resurrected the complaint under a new reference number: ***. Technicians were sent here on 2 March to test for the 4G signal, which was found to be too weak to serve as a connection - this was done using their own modems, showing that my modem was not at fault. Tests were done all over the house and property, with a weak signal being found everywhere. In the telephone call of 18 December 2015, Telkom still insisted that there is 4G coverage of my suburb, Lynnwood Glen.
