Telkom billing for a cancelled line.

In late July & August 2018 I requested a move for my 2 Telkom lines (adsl - ********** 440 & prepaid ********** 573). I received a call back from Telkom saying that the lines can't be moved because they don't have the infrastructure at my requested address. They advised that I apply for LTE and cancel my lines, which I did. Now I'm penalized and charged for a line I cannot use. I requested the cancellation on the advise of the Telkom agent, because I couldn't use the line anymore, not because I didn't want the line anymore but still Telkom keeps on charging me after I paid up the accounts after the cancellation. My adsl line came with a email address which I used for business and requested to keep. I was told that I could keep the email address and will be billed alone for the email address. I was still billed for the cancelled adsl line and my account was suspended due to non payment. And because I was desperate to use the email address I was told that I have to pay for the adsl line just so they can activate my email address and I can request a refund for the money.

Please advise how I can go about getting the charges reversed after cancellation and my money refunded to me.
