303-280-8689

No message.  Hung up on machine.  I am on the national do not call registry

do as I have done call the police once u answer it could lead to trouble they can take control of ur phone that way

Why they calling me for?

I got call today. I answer it & nobody answer back!

this number just called my house, and there is no answer at the other end. This number called after my number after it was registered for the do not call list. If you get a call from  these useles people please leave a comment, very annoying!

i didn't pick up cause i knew it was long distance and i don't have anyone in the states.

Getting calls from this number. No message is left, they just hang up. Caller ID shows Product Dev Cor and 1-303-808689. Very annoying!!!

They're still at it.  Still calling.  Still Product Dev Corp.  Still hanging up when the answering machine picks up.

Product Dev Corp

Dex phone books calling with an automated message to see if I received the phone book dropped off at my door.  Unfortunately, I did receive one and it went directly into my recycling bin.  Waste of paper.  Perhaps they shouldn't have ripped off businesses for so many years charging exorbitant fees to advertise in them.

I answered but no one said anything

I have try the DO-NOT-CALL several times, and they still call.

another call from 303 280-8689, wish they would quite wasting my  time, most likely a scam/telemarketer artist number.
did not bother answering it

I am on the Do Not Call Registry as well  but still get unwanted calls like this. If a call comes in I do not recognize I let the answering machine answer. If no message is left  it cannot be important and most likely a pest.If same number calls again I answer  then hang up immediately to stop the annoying ringing.

Stop calling.

I will report you I'm not insting in surveys I'm on the do not call list you a--h--- I don't want a f---ing call from you again

Recd at least 4 calls from 4 different #'s, all from "product development" , who are Verizon's phone book delivery co. Talked to one of the reps, & answered the survey she gave me.

SOOOOO tired of robo, spam phone calls.  I have caller ID.  I am receiving 8-12 of these unsolicited calls a day.  I would never do business with any unsolicited call.

I do use phone books

Called me today,1st time.I did not answer,cid read product developement. Thats good enough for me not to answer. Does anybody know what their selling? They left no message.

NEVER heard of 'Product Dev Cor' so I did not answer. Am on the 'Do Not Call' list but it is rather ineffective, to say the least!
