Poor service

It's been two weeks that I've done simswap and Pretty the consultant told me she will contact me to check whether my SIM I active or not within 48hours but in vain. I'm really tired of MRP MOBILE to appologise every time as if they will do the right thing. Now im supposed to pay my monthly payments with no service. I went threetimes to their stores where their workers gladly helped me to contact their price MOBILE consultant where I got only promise that it will take within 48 hours. I'm really disappointed about their poor service.
