vodacom refuses to refund or reolve any issues. over 20 hours logged in

Vodacom has no intention of solving my problem or refunding me what is due to me. I have been having endless problems with them from Sep 2022. I had written before on hello peter, and Vodacom said they will resolve it. I’m still waiting. *** and *** These are only a few of the call logs that I do have. They have over charged me, then refused to refund me, saying I used the data. But I was already on the contract of 10 gigs, I was suppose to get that 10 gigs, they gave me nothing more. They stole all my previous data on both sims, each with well 10 gigs, they never replaced it. I was paying R199, they charged me over R400. Again 2 sim cards. 2 same problems. Then they show on my invoices I received 2 devices, I never did, but I have been billed for it. They have called me so many times I have now over 20 hours log in hours with them. I have so many ref numbers with them for the same issue, according to me the owe mw well over R1000, they claim I used data for it. But again, they gave me 10 gig my old contract was 10 gigs. The claimed on my invoice I received some handsets, but I did not, they have no delivery record of it, but they billed me for it. I am lost and do not know what to do. After putting on hello peter, they will v]call me again and I would have to reexplain everything, they= way I have to 10 previous people. All logged. So they cant go back on their system and read, they waste my time and I must reexplain. I would like to know if there is any legal action I can take, if anyone can help.
