Sim not activated after multiple promises from Rain

I have a business that needs internet to run. With that I purchased a Rain sim because of the uncapped internet at a good price. Befire I made the purchase I talked to one of Rains sales people who informed me the sim will be activated within 2 hours of me submitting the necessary document. It has been 3 days already and after numerous phone calls to support agents my sim has still not been activated. We must pay in advance for a service to be rendered but we get nothing in return. At this stage I am loosing money as my personal can not access the internet and return mails to clients. Every time they have the same excuse that it will be active in 2 hours. Do you guys at Rain think it is fair to your customers???
