Over billing my account - Consumer Complaint for Vodacom - Head Office

Since September 2020 vodacom has been taking R510-00 out of my account this is unacceptable as I am only suppose to payR134-00 PER MONTH THAT not What MY CONTRACT SAYS SO WHY ARE YOU TAKING MORE MONEY OUT I HAVE NEVER EXPERIENCED ANYTHING LIKE THIS BEFORE IN MY LIFE. Surely only business contracts have to pay so much I am not on a business contract sort this out or else I am going to hello peter.
