Who called from 6103140107

Getting ridiculous with calls from this number. They need to stop already!

Caller ID says West Chester PA.  Very annoying and seems to be a private number.  Anyone have an idea who or what this is?

I tried calling this number back and actually got a recorded message (as opposed to the usual "not in service" message).  It's Metrix Matrix Incorporated, an opinion research firm.  You can press 1 to supposedly get off their calling list but I've found that always backfires.  

Their home office:

Metrix Matrix Inc.
785 Elmgrove Rd.
Rochester, NY 14624

Called, saying West Chester on the phone.  It rang 3 times, then they hung up.  Annoying!

Caller ID says West Chester PA.  Didn't leave a message.  Will block if it happens again
