I received a call todayat 3:15 pm EST from 1-727-919-2580 (New Port Richey, FL) with an automated message stating it was "Card Services" and I could lower my interest rate to press 1 for assistance. I pressed 1 see to what that call was all about. A man with a foreign accent answered from what sounded like a call center. Lots of background noise/conversations. He identified himself as an employee with Card Services and said my call would allow me to reduce or keep my interest rate on my Mastercard at 13%. I said I don't have a Mastercard and he hung up on me.
