Yeah I also learned from my experience some times it takes 5 to 7 business days to get the points....
I had also called to sdm 1800# on 5th business day of my transaction in the past to inquire about my points for the coupon spend $50 and get 12000 points,CS award me the points and after 2 days I also received an other 12000 points....
I think they (CS reps) until now don't know about it and how to fix it.
