no service delivery

It has been a month and Mondo still could not produce what they had promised. I still cannot access 1 gig of data I need! What is the point having a tablet if I have no data.. They promised that I can use MTN towers but I cannot. It tells me that all mtn signals are forbidden.. I phoned Telkom at least 3 times and Mondo probably 5 or 6 times with no result..No one could help me. Now I am paying them for no service... This is some of the worst service I have ever received.. How difficult can it be? Please stay away from them especially if you live in a region with no 8ta or telkomsa signal, it does not work. I live in Heidelberg western cape and their service does not work. They also have extra hidden costs, I should pay less than 90 rand but my first billing I received is way over a hundred rand and that with no service! Unhappy customer, I have wasted lots of rands on phone calls alone trying to sort out their problem!
