It was a robo call, I answered and a pre-recorded voice announced they can lower my credit card interest rate. It's a scam, they don't even know which credit card I have, then they want you to call them back and give them your credit card info... Such a scam..
Got a call on my cell, came up as Scam Likely (love it when my cell phone tells me that). Decided to answer anyway to see what it was this time. Automated message informing me that it was my "final warning" to lower my credit card rate and help with my debt. Finally got through to a live person, who insisted that she works with Visa, MasterCard, American Express, and Discover. When I asked which card this was regarding, she kept insisting that she works with all the major ones. When I asked again, which of mine is it regarding, she started to try to tell me all of mine. I told her that I don't have a credit card and haven't for the last 6+ years. I then asked her if her mother knows that she makes her money off of scamming others out of theirs. Surprisingly, she hung up on me.
