7 Attempts to cancel contract and no response.

I am not happy with the service at all. I've cancelled my vice contract on the 5 October 2015 with ***. <br> <br> This was my first attempt to cancel the contract. I have phoned numerous times to correct this and received no feedback from Telkom regarding this issue. My first call was on 5 October 2015 with ***. I phoned again on 17 October, 23 October and 2 November and e-mailed on the 16th November and asked per e-mail for feedback on the 3 December 2015 with no feedback on this issue.<br> <br> The e-mail of 19 Jan. 2016 is my 7th attempt to get hold of Telkom Mobile cancellations department. In the meanwhile I must pay the monthly installments on the contract that I want to cancel.<br> <br> <br> <br>
