MTN YOU HAVE DISAPPOINTED ME - LOUSY, SHOCKING & DISGRACEFUL

I took out a 40GB data bundle plus an Alcatel Mobile Wifi during March 2018 so that my brother could use it whilst he was here from overseas. MTN supposedly gives you 30 GB of free data. After one week everything was used up. Basically 50 GB apparently used up, the 20GB for "nightsurfing" not provided and to top it off I have been waiting for almost 2 months for a Itemised Billing Printout so that I can see the actual usage for myself ... nothing has been forthcoming. The package was supposedly R319.00 , they are charging over R500. It is an absolute disaster and a disgrace to receive this type of service. This goes to show who MTN really are, I have had my mobile phone contract with them for over 9 years now and haven't had a single problem. Here I take out another contract and its as if "Mutt and Jeff" are running the show... no joy, no information, I am not using the service, the device is back in its box, it has been there since late March, the device is a piece of flimsy *******, its charge doesn't last long, MTN are breaking the CPA with such relish, false advertising, zero service, unhappy clients are not assisted ... 2 months later ... nothing. I WANT TO CANCEL THIS LOUSY CONTRACT
