I noticed Curve sends a notification and actually adjusts your curve cash balance when you receive a refund. I don’t remember them doing this in the past. This is how it should be, but it would be very helpful if they added a line item deduction of the rewards. As of now the points are just lopped off the top of your balance without a trace (after the push notification).
Additionally, I just did a GBIT for a purchase at Amazon and they deducted the points from me (as if it were an actual return). I could see if they were deducted and then credited again when changing cards (which still wouldn’t make a lot of sense). But no… just lost. That’s pretty messed up. I think the GBIT refund triggers this somehow.
