Husband got scammed

Weldon received a letter yesterday , from a Company ( Carsafe) that claimed that our extended Warranty on my Saturn was running out . Needless to say , he called them and extended the Warranty . I thought that he was on the phone with ALLSTATE so I didn't pay much attention . So then he tells me today that he has a weird feeling about the Call . I found out that the call was to the Carsafe Company not ALLSTATE . I went on the net and found out that this company is a big scam . Weldon was beside himself and called the Credit card company and told them about it . We have to go to the Bank tomorrow and change all our Accounts and get a new Credit card . He beat himself up pretty much ; I told him not to worry and we will fix it . So I found 3 Articles on line ; about this " Company " and printed them out so we can bring them to the bank . I am so upset over that scam .
