Poor service

I bought my partner a cellphone on contract this year with MTN. About four months ago, he reported to me that he is not receiving the airtime that he is suppose to get every month as per the contract and equivalent to what we pay. I reported the matter a month later. To date I have not received feedback, I have contacted the call center, I have sent numerous Facebook messages privately to follow-up but all I get is " matter escalated and numerous reference numbers.

Whilst my partner is not receiving the airtime as per the contract, MTN still debits my account without fail every month. I am appalled by the lack of interest from MTN to resolve my complaint.

I am sick of their apologies I just need this matter sorted.
