Fm my research TRANSCOM ENHANC is a broker of voice services. I don't know who the end user is who is using the caller ID as a cover.

Caller said they wanted to hear my side of a civil suit for a bad check (I do not have checks) The company was in New York, and left the number 1-866-670-6917 ext 707 and ask for Alex People - along with a case number 906457. What they wanted to know was my SS# so they could look up my case file. They knew my name only. I called them on a bussiness phone so as not to come up on caller Id.

This outfit showed up on my caller ID on 3-14-12 at 12:29 PM. No message was left so I looked them up online. It may be some kind of communications outfit or glass co. but I am unsure as they never left a message. I don't know how they got my phone number.
