PORT CHARLOTTE, Fla.- Two CVS store clerks stepped in to save an elderly Port Charlotte man from losing thousands of dollars to scammers. Walter Matheson says he received a call from someone posing as his grandson, directing him to buy $2,000 worth of iTunes gift cards to use as bond in order to get out of jail. “I know nothing about cards. I thought this was a special thing for getting people out of jail,” Matheson said. “He says ‘when you go up there, don’t tell them at all what it’s for, no matter, just say it’s for family.'” Matheson went to a CVS store to buy the gift cards, but his credit card didn’t go through for the purchase. When the cashier found out why he was buying the cards, she felt something wasn’t right. “She said, ‘Mister, it’s a scam,'” Matheson said. “‘I’m telling you, it’s a scam,’ she said. ‘Please don’t buy those things there.” Later that day, Matheson got in touch with his grandson and found out he was okay. The Charlotte County Sheriff’s Office is sending out a warning about the scam preying on the hearts of grandparents, saying to be suspicious of any odd phone call. Authorities say you should try to confirm what your being told first, before you become a victim.
