MTN POOR POOR POOR STAY AWAY

I have a premium Cell phone MTN package my total monthly bill is a average of R2600.00 when I say top package I mean it - as soon as I use more than 25gig of you get throttled? Meaning although u spend a lott of money on a cell contract it means nothing. According to them in the small writing it is stated. People people please don't waste your money. CELL C top package is in the region of R1500. Also according to the sales clerk that means unlimited calls, unlimited data and lots more. So what is my advice.......Hello Cell C can't wait for my contract to end at mtn.
