Incorrect billing and horrible customer care service

Telkom has given me the run around and quite honestly the worst service

I have called numerous times to get my contract canclled with no success for months, when i finally did every consultant i called gave me an incorrect amount for the device fee varying from 6k to 2k. I finally paid the remaining device fee , aparently this device fee was overcharged by their customer care consultants. Not only was my money not returned but you keep charging me a carry over bill for something i already paid for???????

I would like this sorted out immediately and all my money returned !
