This is a gimmick, beware. Do not pick up. I did yesterday and this company has 15 numbers from various US they spoof and use to either say you owe money, lower credit card or have IRS investigations. Linked to 209-456-6789. Bad.
I got a call from this number regarding lower my interest rate on credit cards. Claim to be the card member services for Chase and Wells Fargo. Wanted to charge me $790 to lower my interest rate.
