Dearborn Data calls numerous times per day even though they have been told nhot to call

Left silent message on answering machine were too afraid to identify themselves but my caller id has their number
hoping phone company will allow me to soon block more then 20 phone numbers from calling my phone. My answering machine message clearly states though
state your name and your business or do not leave a message though, but I still have these stupid companies and telemarketing jerkoffs calling

Ohio Guy posted this info. I talked to "Tina" and she took me off the call list (supposedly).

Keep calling and calling and calling and calling.......
Won't stop when asked. when you call the number back it's disconnected. Multiple websites have complaints about them.

Why can't nut bag muslim terrorists target assholes like this. Then we'd all be happy and the extremists would get to kill someone!

STOP CALLING. TAKE ME OFF THE LIST!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I get this annoying calls from dearborn data daily even when I request to be on the do not call list. I'm ready to file a lawsuit

No answer when picked up, after a period I have spent searching and found this info for the company. I recommend filing complaints with the Colorado Attorney General.

keep calling and never answer. is quite annoying.

Hey guys, please listen. This company is calling people and the number on the caller ID is NOT the number you can call to reach them. Their real number is: 303-415-9830 Call that number and you can tell them to quit calling. I did this and still received calls. So I filed a complaint with the BBB in CO. I get an email from the call center manager at this telemarketing company claiming that ALL of these complaints about Dearborn Data are inaccurate and there is no way that they are calling at odd hours or hanging up on people. Let me know if you want more details about this - I want them stopped. Give me your email address and I will forward you the VERY entertaining emails now going back and forth between me and this manager. Hope this helps!!!!

Same complaints as everyone else. They've been calling for a few weeks now, never a response when we answer the phone and callback presents a dead number.

These people called me all morning back on Oct 13th, not sure of theri purpose but I don't want or need to be bothered with these idiots.

VERY VERYStrange ... A call from this number 720-214-0442, asking foir my brother by name and he does not know or even pocesses this number. Very strange ... then asked for his wife "if she was available".

Very strange as only 3 people have my number, 1 is my Attorney, another is out of the country Australia and I am the third person. How they assumed my brother was at this number he does not know about and that he is married too.

WHO are these people?
