Just got a call from this number - caller ID showed UNDERWOOD MEMOR. Answered and got a robo-call identifying as "account services". Yet another credit card scam.
Note: This call came in on a second line that I haven't ever used for personal business nor published. I have to assume they were just random dialing.
Offered to lower my rates on current credit balance. Hah! I do NOT carry any balances so know this is a scam - but, you can't call them back - all you get is a busy signal. Will report on the federal "do not call" site next.
