poor service and no feedback from MTN or their consultant

I have since written a review on MTN debiting my account without my consent. I was called by Mazwi Zuma who seems to be handling my case.I was asked to get an affivadit and other documents so they start investigating ,which i supp**** to Mazwi. I spoke to Mazwi on the 22nd of January who advised me that it takes up to 21 days for for them to do the journal request(so they can calculate how much they need to pay me back). since the 22nd of January i have not received any call to update me on progress. they have been busy with the journal request but no one is asking for my bank statement to make sure that i am reimbursed for my bank charges that i incurred due to them taking money without my consent and this was not provided for. i had to pay 185+- for bank changes for the returned debit order when there was no money in my account. I am not asking for a favor here i am asking for my money that MTN took for my account and the costs I incurred. Today is day 22 and i still do not have an update. This is very disappointing from such a Big company like MTN. No matter how small the amount is to MTN i want my money back. i am tired of being the one calling your office for feedback, is customer service not a priority to you guys?? I need a manager at mtn to call me so we can get this soted out.
