Mtn a big no no!

...still no feedback from useless Mtn...Been with them for 23years...Took a new Data contract out last year.40gig for R199...but I have been paying R299 per month.. now for past to months I still pay R299 but getting 10gigs. My normal phone contract has missing payments from june and still not sorted even after I had to go to my bank for a statement as proof....DO NOT use MTN..They have very very bad service...
