Myself and a lady Kelly who commented on this same number. They call and when you answer, they hang up, they don't leave a message and there is no way to return call.  If this is a legitimate business they need to improve their customer service.  If this is a spam.

I keep getting a call several times a day on my home phone from 814 344 4021  and when I answer they just hang up.

Got a phone call from 8143444021...called back and it said, welcome to Verizon wireless cannot be dialed, try again...something like that.
