T he email deal this summer from La Fontana Italian restaurant near the Port Charlotte Town Center was tasty: Buy one gift certificate for at least $50 and get another one free. That was an offer Marianne Zezelic couldn’t refuse. So the 64-year-old Punta Gorda resident used her Citi debit card and purchased $100 in gift certificates for $50. It was a no-lose proposition.

Except she lost.
