They identified themselves as the Miami Dolphins Identity Protection Service and spoke broken English with a foreign accent. Sounded like a phishing scam to me.
Seems to be legit....Miami Dolphins alumni association working with AARP cautioning seniors about current scams - i.e IRS and Microsoft Tech Support....caller just says to call AARP Fraud Division if you want more info...they do give a number, but you could just look it up online to be sure it was a good number
