MTN DATA BUNDLE NOT FULLY RECIEVED

GOOD DAY

I app**** for a data sim with mtn during the black friday promotion last year the one for a 50gb data sim for R299p.m(30gb day and 20gb night), because i recieved the sim at the middle of the month i was told i was given pro rata data and that i will receive the full value of my contract the following month,after a month i still did not receive the data as promised and the consultant advised me that he would escalate the matter and that i should recieve the data shortly after,fast forward a few months,endless phonecalls and emails later i am still recieving 40gbs instead of 50gb it is not what was promised to me and i have been nothing but patient,the consultant who assisted me Leonard Mokoena and A MISS Teresa Wright have stopped replying to my emails ,i am tired of call centers as i just get transferred or disconnected,i have always been a loyal Mtn customer and if this is how they treat you when you have a grievance then, i am utterly disappointed in how they treat their customers,all i want is to find out why i am not getting the full value of the data and what Mtn is going to do to rectify the matter,and also what they are planning to do about the data that i paid for but did not receive.
