My account has been handed over to legal and I don't owe MTN

<div>I have two contracts with MTN: 1. BA*** - I did an upgrade on this contract, I took a laptop and MTN was charging R539.01 instead of R399.05 The number for this contract is ***.

2. BA*** - for the number *** and I pay R525.68 (this is for airtime, data and cell phones insurance).

MTN was charging me incorrectly (R539.01 instead of R399.05) on the account BA***. I paid R539 for 6 months (from August till January) which is 6 months. R539.01 - R399.05 = R139.96 difference

R139.96 * 6 = R839.76 (That's what MTN owed me). I know that MTN does not refund the customers and what they did was I was not debited in March but now in April you debited my account with R74.60 but I was not supped to pay MTN for 2 months. The credit R839.76 was supposed to be for March and April (R839.76 - R399.01 March - R399.01 April = R41,74 (is what I'm left with). My debit order for May must be R357,27

After the amount was amended to R399.01 I lodged a query through call centre for a refund but I was told that my query will be sent to the billing department, and they are not going to refund me but pass the credit to my account. I was surprised when MTN debited my account this month. May you please assist urgently because I have wasted a lot of time trying to sort out this Issues. My query dragged for months, and I really don't have the energy to wait any longer.

I will appreciate your urgent feedback regarding this matter. Pity I don't have the reference numbers that I've received from MTN call centre all the time when I lodged incidents, I lost my phone early this month so I'm using a new phone. But that is not a train smash because you have everything on the system. Kindly note that I reversed the debit order for R74.60 as I was not supposed to be debited with that amount and I know wating for it to be added back to my account is going to take years for MTN to do that.</div>
