Telkom ripping me off

I took a contract phones end of March at Jabulani mall 2 cellphone deals for R499 which comes with headphones and you should pay R80 extra to get a Huawei watch. I did not get the second phone cause they had to send my information for verification. I had to follow up now and then to check the progress as I needed the phone for my daughter. Eventually I got the second phone just after buying another phone cash for her. Upon activation there was a problem off which they had to log a call since they couldn't activate. I was unable to use the phone for months and ended up keeping it inside the box. Called customer care several times to check if they can assist with the activation but I was unsuccessful. 4 months later I saw a statement and the amount combined is more than 499 no watch no extra headphone. So I decided to call customer service again to check if they could help, then they advised that I should take it back to any telkom store maybe they will assist in taking it or activating it. I went to telkom maponya mall and they turned me down informing me that I have to do a Sim swop but they will not take the phone back since it's not their device. I told them that I missed placed my ID but I have a drivers license, they rejected the drivers license. Now I am stuck with the phone that I don't need anymore and even worse that the phone is not working, yet the debit order will have to go through monthly for stuff that is not even complete. It is not fair. I can't go up and down then be turned away without being assisted
