Data Account increased from R105 to R2147 i

On 19/09 MTN phoned me to inform me that I am due for a upgrade on my telephone. The upgrade was done.<br> <br> On 13 October my invoice came, and my data bundle account (seperate tel number) shot up from R105 p/m to R2147.48!!! - this is a data card, not linked to my phone.<br> <br> I contact 808, *** was given to me, and I requested 3 things: 1) Fix what is wrong, I do not want to exceed cap, 2) I want to listen to the tel conversation to see who is in mistake, 3) sent me itemised billing in order to investigate the legitimacy of the usage. - NO RESPONSE ON THIS<br> Then I send e-mail on 1/11/15 to [Email Removed] requesting the same, *** - NO RESPONSE. My bill came in Nov again - AGAIN WITH THE HIGH CHARGE!!!<br> <br> I phoned today again, get transferred from Zanele to Qobeka, AND NOBODY CAN HELP ME!! 2 hours was spent on the phone with no results. <br> Has MTN got so desperate to get our money to pay their debt in Africa!?????
