Terrible Telkom

I have cancelled my contract in December 2015. I am still being charged and have spoken to numerous people about a refund and cancellation. All make the same promise we will look into it and will refund your money.I have spoken to the manager Levi Makena and he assured me the accounts department is busy with my request and I will get my refund. I am still waiting ??? This is a horrific experience having to pay for calls to telkom and holding on for 20 minutes or more for assistance. I called telkom 7 times in Feb and was on the line for 1:37:24 minutes that costed me R127.03. How fair is this for an error that they made. I can now see why there is hundreds of complaints for Telkom
