Scam...I love how I they want to lower my credit card rates when i haven't had a credit card got over 10 years. Now I wish they would leave me the f~~k alone!!!
Just got a call from this number. At first it was a recording about lowering my credit card rate so then I pressed 1 because I wanted to be taken off of the call list. The man who answered was foreign but spoke English so when I asked to be taken off of the call list all of a sudden he no longer spoke English and just kept speaking in whatever. So I asked to speak with someone who spoke English and he just continued to act like he didn't speak English so I just hung up. This one will go on the block list along with the others.
