Unhappy with service

I am very unhappy with their service, i am a new customer and i received my router and sim card they delivered. Till this day the 11th of Sept my sim card has not been activated. I called them several times and they giving me the run around. One of the consultant even promised to call me back and never did. i have wasted over R300 worth of airtime trying to get hold of them. i mean this so annoying this means i payed for nothing this month.
