Billing discrepancies and unresolved account management issues

I formally lodge a complaint regarding serious billing discrepancies and unresolved account management issues related to my MTN contract.

Contract Details - Contract Initiated January 2024 - Monthly Agreed Amount: R651.39 - SIM Type: Data SIM (Secondary ; minimal usage due to home and work WIFI)

Issue Timeline - 31 January 2024: An unexpected debit of R1176.80 was made . Upon visiting your store, I was informed the contract was "open", which caused the overcharge. The consultant CLOSED the contract to restrict it to the 2GB allocation. - February 2024- February 2025: Regular monthly debits of approximately R651.39 were made, consistent with the agreed terms. - 31 March 2025: Without notice or consent, two debits were processed from my ***.00 and R1005.67 (Total: R2499.67)

When I called to dispute these charges, I was informed-once again that the contract was "open". This contradicts the changes made in January 2024 and confirmed through consistent billing for over a year.

I have repeatedly requested: - Proof of who reopened the contract, as I did not authorize any changes after the initial closure in January 2024. - A detailed data usage breakdown to justify the excessive charges. One of your consultants confirmed only 3GB of usage, yet my statement reflects 60GB, with no further explanation or breakdown provided to date they still haven't resolved this matter or refunded me my money.
