I have been having a running battle with telemarketers wanting to clean my air ducts.Since they usually give me false company names, addresses which are out in the middle of a field, I decided to play along to set up an appointment.They are supposedly ... Express Home Services and their call back number is (supposedly) (647) 761-3232 but there is no answer at that number.  They may not be answering because they have caller ID and know that I am pissed at them.  Dunno.

They called me and would not respond, no idea who they are

i just called the number back which just called here and it says the number is out of service! how did they call then? must have spoofed the number

Yep.  Called 10:50 am on January 30.  No voice on the other end.

I just got a call from them. I got a name and company name but when i asked for a call back number the line went dead. SPOOOOKY! LOL Lets see how many facts we can get and post them.
