Excessive Billing, Bad Attitude and No Response

A complaint was raised on HelloPeter on the 1 June 2015 in connection with an Excessive MTN Billing Account. Response was received on Wednesday 10 June 2015 whereby MTN will investigate and that the line is activated and currently in use. I received another bill for R5800, this amount is due after the line was deactivated, and I am still waiting for the itemised billing. I tried to contact the Customer Services number and the response was services currently disrupted and this after they have been on strike for a month. I have a cellphone number for one of the representatives and she was so rude that the she refused to help and put the phone down when I call. The line has been deactivated again. Please could a representative respond to my complaint. This is ridiculous that I have to wait for over a month after numerous emails have been sent for MTN to forward me the itemised billing of files downloaded to the said amount.
