Male caller posing as Wells Fargo card services agent to discuss 4 potentially fraudulent (and large) transactions from Dubai on my credit card. He had my name, phone number, home address and last 8 digits of card. When he asked for my SSN to pull up my account to verify charges, I became suspicious and hung up. I then called Wells Fargo Customer Service at the regular number and agent saw no charges and my card was active (caller said he was shutting down the account and sending me a new card.)
