2 AnswersWomen's Health8 years agoWhat to do after being robbed by a fake insurance company?
A couple days ago, my father called a company named, "Automotive Professional Resources", he had been receiving several notices like the one in the link below, well he called and he gave out all his information and credit card number. Not even an hour later we found the webpage in the link below. By then it was too late because he had already given his info, so the next thing we did was called his credit card provider and they told us the only thing they could do was report it stolen. This 'company' had already charged $300 of what would be the first 'payment'. I don't think he'll be able to get his money back, what is there to do when you get scammed like this? Should we call the 'company' and confront them?
