Telkom's worst service ever received

Good morning

Please assist with this matter I have bought a contract phone with Telkom on the 26 April 2018 only to find that the phone did not have the applications or features that I needed so I went back to cancel it on the 28 April 2018 so it is still on the free cancellation period of seven days. I was given a reference number ********** 9 then days later I went back to follow up I was told that there is no contact number to follow up on the call was logged with their support team till this day I was not contacted by anyone and my account has been debited for a contract that I cancelled.
