Getting debited for products that I don’t have.

Getting debited for products that I don’t have... Called in to order a mobile wifi router in August this year which they then did a coverage check for LTE. I was told that all is fine and they sent me the router. Once received, plugged the device in and there was no signal. I called in to double check and the person said that there is no LTE in your area. I then had to send it back so the courier collected it from me. I am still getting charged for this device even though I don’t have it anymore...

I app**** for a fixed internet line of which I cancelled because They sold me something that didn’t work so I didn’t have another choice. The installer called me a few weeks after the order was placed and I told him that I have cancelled the installation. I was called again by a installer a few weeks after that and again I told them that I have cancelled it and he told me that Telkom is disorganized and that he was sorry to bother me...

So now how do I get that money back, paying for something I don’t have....? I also went into George Mall to Telkom. Explained my story and the lady said that there is a 021 number that is going to call me and up till today I am still waiting for this call. Can anyone assist me?
