MTN not doing their Job, *********** and we must pay the price!

After more than 20 Calls to the Call center and endless emails they just cant do their job by rectifying our account! According to them they changed their systems and cannot locate our payments! We have spoke to several call centre agents, emailed all our proof of payments to about 10 different people, assistants from the stores have tried to help us but they are just not fixing our account! We use our cellphone number as reference so we cant understand how they cant seem to fix it! Instead they keep on cutting our lines! On sunday when we were in the MTN store we could not perform our new upgrade that is due and then also saw more than 10 tickets thats open for this situation that is just not being delt with! I wonder who is going to compensate me for the loss of business due to them not doing their job!!!! Again this morning both myself and my husband services are suspended, all our proof of payments have been mailed with contact number as reference but they just cant seem to do their job and sort it out! I dont know how they cannot allocate our payments even after we send an detailed email with the old account number and the new one!! Sort it out MTN
