Got the same phone call, they have called me 3 or 4 times a day for the past 2 weeks. Picked up tonight guy said he was from platinum select and wanted to send something to me, knew the last four of my husbands credit card and my home address. Then talked super fast about some offer and needing to cancel within 90 days when I hung up the guy called 5 times in a row before givving up.
Said they were from my Platinum card and had my last four digits and address. Tone, conversation, unwillingness to provide information: these people are up to no good, whatever it is they're doing.
