Who called from 6366251531

Our company owns the number 888 442-8003, and for whatever reason, the jerk is telling people to call our number!  don't know what it's all about, but it's disturbing!  Please disregard!

Same thing a few minutes ago

I answered, a man said hello then hung up

Same as everyone else, couldn't hear what he said but he hung after saying it. Calling back says the number is disconnected; maybe they are making a call using Skype to our phones?

Same Man's voice, said hello, I said hello and then nothing.
