RAIN is frustrating my family with no connection!

Since we connected on Tuesday and made a payment of R479 the network is really not what they are advertising, we went through the ricking process and all the things that they asked but there is just no signal on this thing, my wife send them two emails and all they say is one of our personel will respond but no luck we are still waiting,we have now indicated to them that if they are unable to solve this problem they should just give us our money back, but they have not yet responded all we want is what we paid for WIFI!! or our money back not run around while they are playing with time on the money we paid the frustrating thing is the lack of communication while they know very well that I will not step in to a store and get some feedback fix it or give our money back!!
