That's strange... Btw you were connected to wm customer care or normal customer care. I've wm so was assisted by wm customer care maybe that made a difference not sure.
You can simply call them and they'll credit it manually. I had the same issue in 1st statement and after 7 days I called them it was credited. In second statement it was auto credited like always...
Yes I called Customer Care they're saying received for Feb although made 1.2L txn so would've received 12k and they're saying contact iShop for pending reward points not received.
But if I haven't done any other txns then how could it be for something else. Someone else also got ig. Anyways I'll see with customer care if they can figure out.
