MTN changed payment due date in contradiction to their sms send to customer.

PLEASE NOTE COMPLAINT NR 2 HEREAFTER IS MY COMPLAINT. Complaint borned from this problem 1. MTN DUE DATE PROBLEM NOT SORTED: Please note that my september statement does reflect due date earlier that MTN written assurance that it remains the same after MTN change of dates to load value added services 12 days earlier. MTN statement DUE DATE : 25 September. 3 days earlier. My due date for this contract is 28th of each month. 2. LOST OF 34 MINUTES on 26th AUGUST MTN cancelled 34 minutes of my value added services on 26th August. Minutes that was LOADED ON 8 JULY According to MTN these minutes were only valid for 2 months. Does that relates to 60days?? That the 34 minutes were left over from value added services loaded on 8 JULY. MTN then change dates and value added services got loaded (12 DAYS EARLIER) on 26th JULY instead on normal 8 August. The following services are loaded on 26th August. ONE MONTH LATER AND NOT FULL 2 CALENDER MONTHS AFTER THE JULY VALUE ADDED SERVICES LOADED ON 8th JULY. MTN says that by the 26th Aug it was allready 2 months and more after the minutes/voice was loaded on my phone and therefore becomes invalid and they removed my 34 minutes- EMPHASIS minutes only valid for 2 months. MTN are loading value added services 12 days earlier. I received 2 invoices for JULY because of MTN changing these dates. One of these invoices was not for a full calender month. 3. STATEMENT PAYMENT DATE WRONG: DATE OF PAYMENT IS ALSO INCORRECT. I paid by EFT on the 28th JULY. MTN August statement shows payment date 30 July. All previous statements reflected the date of actual payment. REF: 1- ********** 814 28 Aug I queried the LOST 34minutes. I was told query resolved. But MTN did not reload my 34 minutes or did not inform me why. I had to make 2 more calls before MTN informed me that those 34 minutes are lost/ taken away/ FOR EVER due to be older than 2 months.
