Who called from 2134570352

We received a call from a business colleague with a 520 area code, yet our caller ID showed 1-213-457-0352.  We tried calling back but it was busy. The company name does show up on Hoover's Business Directory.

I received a call from ? with a caller ID of 1-213-457-0352   TSI, I also tried to call this number back several times and always received a busy signal.  Do not know why they would be calling me.

Received call from 213-457-0352 TSI but when I answered no one was there.

Called from 213-457-0352, no one on the line, considered it likely a tele-marketer and hung up on them...

My husband called me at work, and that number showed up on the caller ID!  Very scary as he was calling from our home
