Over Charged for PSD Data? That I never spent

I have been an MTN customer for the past 4 years with a data contract for my Ipad and my wive's computer. My average spends over the past couple of years sits at about R600 - the contract cost approx R380 and that's for 1 GIG - I normally watch my data like a hawk - as I know that out of bundle rates are expensive - hence I end up buying a gig or two to get to the R600/R700. <br> <br> This month - after checking my MTN Active - I have an invoice for approx R3200 ?My wife and I have wi-fi at work and at home - so data is only used when we are out and about. The invoice says R2200 of data- with no explanation. I could not have used that data.<br> <br> My 4 problems:<br> <br> 1) The MTN app on my ipad hasn't worked in 3 weeks - so I can only monitor data on MTN Active<br> 2) On the MTN Active portal - the line item shows approx R2200 for data - and the amount of data shows 0? that doesn't make sense. <br> 3) I have raised 3 queries - 2 online (no feedback) and I went to MTN Rivonia to open one in person.<br> 4) I have been told I cannot put a limit on my account so it doesnt go over<br> <br> REQ:*** - please advise?<br> <br> On a positive note - Tshepo Selepe was a pleasure to deal with! I will go back to MTN Rivonia anytime!
