This is some kind of scam or sales pitch. We get called by this number once or twice a month and never answer it.
If you ask to be removed from their list they know you are there and probably sell this information to telemarketers.
called me a couple of times, once they asked for me by my first name the second time it just said "Hello" I never picked up the phone. I never answer the phone if I do not recognize the phone number
