Кто звонил с номера 9030000000

silent when I answered, didn't identify them selves or who they were calling for.
I hung up.

No one on the line when I answered.

There was no one on the line when I answered.  They call at least six or seven times a day!

Been calling several times a day now all week long. I don't answer so I don't know who it is as it only shows Unknown Name.

I have been getting these calls too. But I dont answer them. I was wondering if anyone else was getting calls. the caller id it say unknown name. its probably a scam trying to see if it a working number maybe!
