Adding things to account without consent, debiting it and then not correcting it AVOID VODACOM

Vodacom have added a higher insurance plan on my account without consulting with me first (but not just for one month, they added it to my account for 2 months on one invoice) and then refusing to help me to get it resolved, even after asking them repeatedly to correct it for almost an entire month(started asking them to correct their mistake from the 8th of January). I have spoken to so many people and not one of them has advised me that they will escalate this matter, after many attempt to get them to correct it before end of January. After over 15 phone calls, 3 emails and hours on the phone they still debited the amount that i disputed and still tell me when i call again that some of the people never logged my calls asking for them to correct the amount And then ontop of it all after debiting the amount that i have disputed and called to get rectified, they still want to proceed with that this month.(When i called again yesterday they said that there was no comment on the system of me requesting for this to get correct, after multiple calls and emails stating that this is their mistake and they have to fix it )

I do not recommend that anybody use Vodacom, because they add things on your account without your consent, then refuse to help with the mess that they made on your account, and will still tell you that it will get fixed before debit date, and still debit the amount that is disputed.
