Member points used without my permission

[dep1]

I recently discovered that 50,000 rewards points were used to “redeem” a gift card. I did not make this redemption and do not want it. I tried resolving this with a phone call but was told that once a gift card was “redeemed” it was mine. I was under the impression that AARP was concerned about member fraud. Apparently not. This is very disappointing.
