Incorrect billing

I have placed below on the 3rd of Feb with the response that somebody would contact me, but nobody has yet contacted me and now I am receiving SMS’s that my account is in arrears. Review wrote on 3 Feb: I am battling now for almost a year to get my account sorted. Vodacom keep on charging me for an extra 250MB data which I don’t need. I have asked the call centre to take it off since March 2019 and they advised me it is done, but it never was. With my upgrade in Aug last year I have also asked once again to take it off and I was advised as well that it is done but still I get charged for it. On invoice H5-HCG26, dated 01/01/2020 I noticed that another charge was added for calls local, R166.99 (excluding VAT). I have 344m12s credit on my account. I have now only paid the amount of R408.15 on my account which is the fixed amount I have signed the contract for in Aug and expect Vodacom to credit my account for the amount of R54.78 (excluding VAT) since Aug 2019 as well as the R166.99 (excluding VAT) charged this month.
