HI Jul ,

They are not selling any product .or your Data's. your giving a wrong information about this company.

Rings one time and no message is left. Comes from Chicago area.

Calls....Calls..

Stop calling me!

Phone calls from these numbers started calling me Thursday April 8, 2010 and they call about every other day. I called one of them back and the voice mail stated I had reached Blackstone Marketing Group, I researched them and also got the company name DataPrompt International, both companies are based out of Chicago, IL. I left a message that I do NOT want them to continue to call me because of course no one answered and they continue to call me. (312)000-0000   (312)423-4025   (312)423-4101  (312)423-4100

calls frequently!!!!

I had the wrong number to call, it is 312-423-4100

Call the main number, 312-423-4000 and ask to talk to a supervisor.  He will get you off the list (or at least that what he said)

They call all the time - never leave a message - don't answer the phone when you do answer - please get them to honor the no call lists and stop calling people!  I would love to get them to stop!!!

They call daily! But no one is ever there when I answer. The number is listed as the FAX number for DataPrompt International in Chicago. I have reported them to the do not call list and sent them an email informing them of that and asking them to stop the calls.

"Marshall from the Blackstone Group",  and I asked to be taken off the call list

called at 11:53 am and asked for me. I said I wasn't home and they said it was a courtesy call. while a lady was telling me this, it sounded like someone else picked up the phone and was listening. no one else in my home picked up the phone to listen. strange. this sounds phishy.

I can set my watch by their phone call....9pm in charlotte, n.c.  every night right on time...stop them please!

LEFT NO MSG - WE DID NOT ANSWER - UNKNOWN CALLER

calls all the time!!

this number calls freakin everyday.. They just hang up.

rang at 10:30 PM...no one there

Caller ID:

I found this web site for this number.  It sounds like a data collection company.  As soon as you answer the phone the time is documented automatically which is why there is nobody on the line when you answer.  The information about when you are home is then given/sold to different companies. This is my guess anyway.  :)

Leaves no message. Somebody please break their autodialing machine.

called twice and hung up.

Do not know who this is...
