I am laughing at this one....got a call and the caller id showed... Invalid Number...how funny is that? They aren't even trying to be slick anymore. Of course I didn't answer, they listened to the outgoing machine message and then sat on the line for about 30 seconds (I could hear call center background noise) and then they hung up on the answering machine.

I am apparently now on their hit list....three calls a day since the 10th. Still not interested in whatever they are "selling", still not answering their calls.

trade business magazine - call center boiler room, calls every three months, or constantly if you don't answer, to say that your free trade magazine subscription needs to be renewed, and then asks for field of employment info so they can send out more peripherally related trade magazines.  You will never get off the call list and will keep sending you trade periodicals anyway, even if you say that you don't work in that industry anymore.

Today CID showed INVALID NUMBER - again, lovely musical introduction blared before switch over to loud call center and moron asking for long gone employee.  I set the phone down on my desk next to the keyboard so he could literally listen to me type this today.  He held for 2 minutes and 13 seconds!  I believe that is a new record for wasting their time!

Calls every single day at 9am, then 11am, and again around 3 or 4pm. Never ends.
