Who called from 2130000000

Last couple days I get the same 213-000-0000 and when I pick up no one answers... same as everyone else

first time being called from this number. Looked like a weird # on caller ID so I just picked up receiver and immediately hung up. Will block call if it continues.

I answered and the automated voice starts with Shalom, and continues in this foreigne language

Very annoying! Calls received on my cell. There is some sort of a pre-recorded message in some foreign language, sounds Arabic.
Who's behind this? They need to be stopped!

Called twice in two days...left a voicemail the second time...in a different language, I think it was hebrew.
