Who called from 2136230000

Just got a call from this number after another 0000 call from Texas this am.  No message left by either.  

This one supposedly belongs to:

Acme Trading Corp
Address:     18895 Arenth Ave City Of Industry, CA 91748
Telephone:     (213)623-0000

I get this number on my caller ID after I call someone and have blocked my number. I work from home, so I do *67 when making outgoing calls. I just did one today and then this number appeared on my caller ID. Talking to a co-worker, she noticed the same thing. If you *67 when the person calls back, this number 213-623-0000 Pade Vavra will appear. So strange, but happens every time.

yes it is

I use google voice and added them to my nuisance caller list...straight to voicemail for them.

I just change my number to an unlisted number. I am paying extra NOT to receive unwanted phone calls and now I receve calls from this number.........HELP???
