Irritated with the service

I have been needing internet for a while, I asked my friends who is the best LTE provider so that I don't have to wait to be connected. Rain was the number one choice and I am sad to say that I have had nothing but a bad experience and bad service. I picked up my sim card at a clicks and made an error by ordering a sim card instead of activating the sim I purchased, I called and canceled the order and redid the transaction. The website and app both say that my order is active but after 4 phone calls, I still have no internet. The latest is that my account is at billing and should 'hopefully' work tomorrow. Why can't it be fixed now? The funds are there, 2 amounts actually because I haven't been refunded for my error yet either. So why can't you just switch me on?
