They deliver sim cards which don't work

I've been using rain ever since they came into the market. Their service has been excellent until recently. They are now becoming too big headed and dropping the ball. I upgraded to their Rainone package and they delivered 2 sim cards to me 3 weeks ago. I've made them aware ever since the delivery that I need someone to contact me and assist with porting my numbers to them. No one has phoned ever since. I phoned in numerous times and they keep on telling me lies that someone will call me back. I've had these sim cards for 3 weeks, but they are now useless to me. I just spoke to a manager by the name of Dylov who refused to give me his surname because he knows he won't do anything about my complaint. This is so frustrating. I'm now considering moving over to my old service provider because you are now just like them. The only difference between you and them was your service, but now you are just as useless.
