Cannot cancel contract

Good Day I have been to Telkom Bluff to cancel my contract at end November .this contract has not been cancelled as yet & has all been blamed on the cancellation Dept.i have been several times to the bluff store and even dialed the 181 number and Facebook Messenger with no help. I have been told several times that this matter has been escalated. The manager of the bluff store said that I will be reimbursed my January payment & even get LEGALS to call me but I am still waiting. How much longer will I have to wait for this to be sorted out.
