Telkom service is **********

I have sent a request to Telkom in November 2017, a month before my contract terminated to cancel the contract upon expiry. Its February and Telkom is still deducting the amount for the mobile data. I have been to Telkom shops, been on calls with billing department but no one seems to know what is happening. Telkom is not helpful one bit, they are quick to refer your query around with no resolution. I am so disappointed with Telkom and regret doing taking up contracts with them
