Telkom Mobile did not cancel contract as requested

Reference Previous complaint *** - Still not Sorted out Mobile Talk called me in the 2nd week of June 2014 offering an LTE modem & 10G + 10G a month data contract. The sales person Banica said this contract was a 36 month contract. I stated that I was not interested. Next day I received another call from Banica stating that I could take this on a trial basis with a month by month option to cancel if dissatisfied. This was all recorded on Mobile Talk side and they have admitted this is correct. An LTE modem was dropped off at my house. I received no contract to sign. Data was being used up at an incredible rate even when the computer was not being used. I logged numerous faults with Telkom Mobile with no positive outcome. I have sent 3 cancellation emails,on 20th August 2014, 22nd September 2014, & 6th October 2014 (Reference numbers TTD***, TTD***, TTD***). I also sent a Telkom Mobile's Customer Service Request for Service and Contract Cancellation Form. Telkom's Hellopeter reference number is SM115308 . I have not received any feedback or confirmation of cancellation from Telkom as yet.
