Rain custome service is horrible.

I just made a purchase of a Rain sim card, via Mr Delivery. When activating the sim, I didn't see anywhere where I had to enter SIM details. My purchase was processed, so I assumed SIM details are entered after a successful payment. So I called customer care because I don't know where to enter them, turns out I made a new purchase and NO ONE can enter the sim details for this sim card to be activated. A purchase that was made less than an hour ago. No one at Rain can alter it??!! NONSENSE!!! I asked for a refund, WOW, 7 freakin working days!!! So I should wait till then to get data??? Rain, I'm disappointed shame.
