This number has called me 3 time this morning in a 30 minute span. When I answer there is no one there. It is really annoying as they are calling very early in the morning and waking up my family! Also, I looked into Avatar Tech, as the caller ID states, and on their website it says that their information is being used in a caller id scam.
This number has been calling me several times a day for about a week. Same as you guys. No one is there when I answer and when I call it back it says my call did not go through.
