I never even heard of CARMAX until you mentioned it and this number rang on my Obama which only about 5 people even know this phone number!!! It has not been registered with any business, whatsoever, so now explain that one!
Rec'd a call from this number - at the DMV. The guy apparently felt kinda stupid when I told him who they'd called, hung up on me after I stated the business and a do-not-call preference.
received automated call from 313-355-5249 at my work number telling me my auto warranty was about to expire, I let them walk me thru to where they said an agent will call me back. call came from 202-803-4977 and they asked me to verify the auto, I asked what they had for me and she hung up. they are clearly scammers trying to act like they are doing you a favor. I called both numbers back and you only get a recording to press 1 if you want off their list.
