Cancelled LTE not cancelled

<p>From the time I took out the LTE contract I had nothing but poor signal. After logging many calls I was told that due to the signal issue I could cancel my contract without penalties(from March through to October). The contract was sent through for cancellation, not done. After follow up phone calls and many promises of escalations and return phone calls by manager on hand (never done) I went to the fourways telkom office and submitted more paperwork and got yet another new ref number (November). Still not done. In december I called the call centre and was told that the cancellation had been sent through to billing but hadn't been acknowledged and that they would escalate and issue a refund. This still hasn't been done. Who do I have to beg??</p>
