I see people on doctorofcredit also reporting similar issues.
was on phone with chase , first claimed never existed and dont know what i was talking about , then said offers can change and be removed w/o any advance warning even though t &c dont specify that .
I asked why specifically this offer was wiped clean showing no records not as expired or redeemed they couldnt answer that and eventually when I pressed them on that they hung up on me.
So any one who spent money expecting anything back is out of luck if the offer was removed from their accounts
