LTE free Data and Provision

Firstly, I upgraded my contract on December 11 2015 and was told I would get free 30gig LTE data that would be valid for 30 days. I received the 30 gig data on the 30th of December 2015 but it was cut on the 11th of January with 26 gigs still to use. I've logged about 3 requests and this hasn't been sorted out because I was charged out of data bundle rates when in fact, their employees messed up by not loading that LTE data on the 11th of December when I upgraded. While I've been waiting for that to be sorted out, My monthly provision is supposed to kick in on the 21st and it's the 25th now and that hasn't happened either and all the employees keep telling me is \I'll log a request and I'm sick and tired of hearing that. I actually wish for another service provider to buy the contract out of mtn once all of this is sorted."
