These folks have called me now five separate times and hanging up on me. Every time I call back, all I get is the weird screeching like they are a fax machine.

JA jewelry show calling. Keeps changing their number, what a scam!

Just received a call from (647) 351-8128 on my cell that said it was from Ontario, Canada.  I was in a meeting so hit decline, then called the number right back at 10:28 AM (on 4/19).  I heard the following message:  'Your call cannot be completed as dialed, 2-i-i." Then the line drops.

Caller left Message from Robert Harkee ?  with Research - wanting copy of resume?   This is a business number they called and didn't say who they were looking for.

Just called again - just about 24 hours after 1st time.  Didn't answer.

Actually they left a message this time - it was an automated message from Leica Geosystems about the "Hexagon" conference.

received a call from this number at my direct line at work.  I didn't answer and they didn't leave a message.

Call received today: could not hear voice on the line beyond a few crackly syllables.  Did reverse phone lookup online and found this website.
