Vodacom debits my account for a ********** account

I informed Vodacom on the 16th of September 2021 about an extra amount on my account only to find out I supposedly took out another contract. I submitted All the documents they requested and 3months later still no progress. Then when I posted the communication on fb I received a email on the 10th of January saying fruad was detected in Nov 2021 yet Noone informed me. Then on the 18th of January I received a email to say the query is concluded BUT WHAT ABOUT MY MONEY YOUR DEBITED. and to crown it off I received a bill on the 19th that includes those ********** NUMBER. yet vodacom goes around looking for new people to ***** from... And for 3 month you get the generic response, sorry for the inconvenience we will get back to you. I'm sorry they are the worst
