Stay away from MTN Sky Supreme Package

I have the 'top of the range' Sky Supreme package and it is near the end of my billing cycle and the throttling is so bad I can barely get onto Hello Peter to complain about this appalling service. To make matters worse I purchased an additional 6 gig bundle so that I can at least run my business. MTN tells me 'sorry the system on the Sky Supreme will not acknowledge me buying additional data and will continue to throttle me so I have an unusable and non-existent service' So I am now R400 out of pocket and still have zero internet service. This service is pathetic.
