My e-rewards account all of a sudden showed an additional $10.

On checking my account statement, it said "Earn Now Game Universe : Purchase Credit". Now I clearly remember signing up for the Infone stuff and getting the credit immediately which is still there. But Im sure I didnt signup for this game universe stuff.

Anyone with anything similar? Do you this other site has my CC info and would I need to cancel so that i am not charged?

Cheers
