LTE Contract not Delivered - Contract ***

I took up a LTE Internet service from TELKOM after flyers were distributed around our suburb in July 2014. The contract was entered into in August 2014. There is no LTE signal in the Lynnwood Glen area, and will not be one for the foreseeable future, so the modem substitutes a 3G service instead. I informed TELKOM of this in October 2014, telephone reference ***2, and nothing was done - there were repeated calls to TELKOM on this unresolved problem using this unresolved reference. Finally, technicians visited my home on 2 March 2015, and confirmed that there was insufficient LTE signal strength to establish an LTE connection. Since then nothing has been done, despite calls on 11 March 2015, 22 April 2015 21 May 2015 and 16 July 2015. I cannot accept this contract anymore, and wish to be reimburse3d for its cost minus any data that has been used.
