Did you use your card at a Dominos close to your home? Reason I ask I started getting charges of $150 at the same shell station 50 miles from my house. I got the card cancelled and was reimbersed. When I went to use my new card at my local shell station the card wouldn't work as a debit card. So I went inside and told them my 'debit' card wouldn't work. The two employees looked at each other and then told me it would run OK as a credit card.
