Vodacom not helping (*****)

On the 25th of April 2021 it was brought to my attension by sms that contracts on my name were approved by Vodacom. I as soon as possible on the very same day called Vodacom to inform them that these contracts must be cases of ***** because it was not done by me. The very next day I also went to my nearest Vodashop to report it. Since then I have been to the vodashop 4 times. I must have spoken to 20 consultants of Vodacom over the last month or so. I have handed in an Avvidavid and did everything that was expected of me. When I call Vodacom I am being forwarded from one division to the next. My account use to be R640 per month but Vodacom allowed the ******* contracts to run untill my billing stood on R5081.12. I have tried my level best to solve this matter with Vodacom. Today is the 7th of June and after so many promisses of we will call you back in 24 hours and numerous ref numbers nothing has been done. Vodacom still want the R 5081 from me! How difficult is it to fix this and give me my correct billing? I have been with Vodacom for more than 20 years and feel that this is not the way to handle my case. Unhappy customer C Du Toit
