I have always understood that credit card provider will never cold call a customer. Wife order some lotion and shampoo this AM on line from a company she has used for years. About thirty minutes ago a call came in saying they(??) had detected some suspicious use of the card. I automatically concluded this was a scam, even if they did have the card's last four digits. Hung up and had wife call credit card customer service. Provider's fraud prevention help told her there was suspicious activity using the card this AM after she had made purchase. New card will arrive in 8/10 days. She verbally gave vendor her card number. Any ideas how her card number was obtained on our landline through Spectrum? Help appreciated
