Who called from 3868685058

They called several times today and twice in one hour.  Very annoying and it just hangs up after I answer it.  I called the number back and it said "mailbox is full."

They call every day, but when we answer it sounds like a machine about to kick in and then there is just silence.

Calling and making fun of names an insulting the whole time on the AM.
tried to call back, "mailbox is full, can't take an further messages"

Got a call from 386-868-5058 this morning at 10:25am. It was someone from a company called Sunworld trying to sell me solar pool heating and solar hot water heating. He also mentioned chlorine generators. He stated that he was going to have folks in the neighborhood today and that they would like to stop by to speak with me about having those things installed.

I have received calls from this number twice now.  There is never a message left and no name comes up on caller ID.  When I try to call it back,  it just rings and rings.
