Exorbitant Billing

I took out a 2 gig data card with mtn over 24 months ago. During this time i have never use more than the 2 gig on the card. Further to this I assumed that the account being a 2 gig data card had a data usage limit. For most of the 24 months my account was around R129 or there about. I have never exceeded my account knowingly with this sort of amount. I have always checked my indicator on my data card for usage to ensure I pace myself through the month.<br> <br> During the period 13 July 2015 and 13 August 2015 MTN charged me the following.<br> <br> Invoice 2015-08-13 total day usage: 5228.67MB<br> 5228.67MB - 2048MB (2GB monthly allocation)=3180.67MB<br> 3180.67MB X R0.87(out of bundle rate excl vat)<br> R2767.18 ( excl vat)<br> R3154.59(Inc vat)<br> <br> This is ******ion. Ho would I knowingly spend over R3000 on 3gigs of data. I would have thought that MTN would at least have the decency to inform their customers that they exceeded they allotted data usage. I think this is a clever ploy from MTN to ****** money from customers. I don not have this money. I have been out of work for nearly 9 months and are just getting back on my feet. This is unacceptable from MTN. <br> <br> I say again, I do not have this money <br>
