Bad service

Good day

I have had an MTN contract for the pass 3 months and I am being billed more than what I agreed on, I am suppose to be paying R872 for the phones and insurance included every month you debit me a different amount which ranges from R1000 to R1100 which is unacceptable. Secondly I called the call centre today and wanted to find out how much I am being billed and Sibusiso, the consultant advised me that she is unable to open my invoice and is unable to tell me the amount nor have I received the invoice and you are deducting after 12 am on the 31/05. How will I know how much you debiting?
