Answered the phone from this number.  Girl said they are with REPOWER AMERICA.  I looked online - green energy site.  Why are they bothering ppl with "Do Not Call"  #'s?

I called back (*67) and let it ring about 30 times w/ no answer. I added the number to my Google Voice blocked call list. If they call back they'll get a "not in service" message. For those not using Google Voice, request an invite at voice.google.com. It's a great free but by invitation only service.

Getting calls from this number on our cell phone in MEXICO.  No message, no one there when we try to answer, even on the first ring.  How can we stop the calls?

I do not remember the name they said they were conducting a poll. Caller ID read "Marketplace On" but that was not who they were polling for.

I've been getting waaaay too many calls from this number as well.  Just for all of those equally annoyed recipients out there, calls are from Marketplace On First, 4651 1st Ave SE #2, Cedar Rapids IA 52402.  Some friggin' marketing b.s. joint!!!

Whenever ou answer your phone they hang up.  When you call this number it is either busy or no answer.

Multiple calls today.  I did not answer, and I won't if I don't recognize the number.
Did a little research.
What is Repower America?  Marketplace On  4651 1st Ave SE #2, Cedar Rapids, IA  52402.
Stop 'em!!!

No answer. No voicemail. Keep calling. I am on the do not call list.

No messages left, but 4 calls appeared on our called ID within an our today.

They identify themselves then hang up!

I am getting average of 5 calls a day from Marketplace ON. They do not leave a message and I can't get to the phone fast enough to answer it.

got a call from this number while at work. Called it back on break... and it rang... rang... rang... waste of my time. only called because 2 family members are in the hospital, it was after business hours!

Received a call, was not available to answer and no message left.

This number has called me 5 times in the last 6 hours, and twice yesterday!  I just had my latest call & it is 8 pm!  Absolutely ridiculous!  Thanks for the tips people!

This # keeps calling me I have gotten 6 calls with no left message.

They began calling my cell phone this week.  I won't answer because I don't know who they are.  I'm tired of seeing them on my caller id.

Thay called me three (3) times. I did not answer.

Why do they keep calling....I'm up in NH and they call all the time---If it's a political poll--we voted last week and I'm still getting these calls...WTF!!! So annoying!!! Thanks for letting me vent!

annoying missed calls and no message. no answer when i call back or it's busy.

319 294 7021  Do you have any idea what the point of the calls are? I am in Nevada in a very remote location and I am baffled by why I am receiving many calls from this number. Is there fraudulent intent? I work for a gold mine and was concerned that there might have been some link there. I did the do not call registry and will pursue the other 2 suggestions. How did you find the address? There's always something.

Got calls from this number and about a hundred others.  My solution?  I save the caller's number and identify it as NO.  I have about 25 callers identified as NO.  I then turn the ringer off for all of them.  It doesn't stop the callers, but it stops me from getting up to answer the foolish recorded messages or hang-ups.  Eventually, they give up.

I have been gettign calls from 319-294-7021 3 times a day every day for the past 2 months . The caller ID says it is Marketplace something sometimes I pick up real quick and hang up just as fast. They won't leave a voice message. National Do not call registery cannot do anything about the calls. But I have been told I can spend money to get equipment that will stop the calls. Who can afford to buy equipment to stop these people. I also am getting a lot of calls from others who are doing this. It is a pain in the butt, but I will continue to ignore the calls.

If they call when I'm sharpening my knife collection, bad things might happen.

They have been calling me 2-3 times a day for the past week or so. Again they leave no message and When you try to call them back the line is a busy signal. So, Just about and hour ago I decided I was going to answer the call. They asked for me by my first name I said she was not available could I take a message.. They said that it was just a courtesy call?? I had to ask 3 times from where and they said something like RR oregon? And asked if they have a number to call back and she said no and hung up.

I've been getting calls from this number at least three times a day, no matter what time. I never pick up, but when I call them back I just get a busy signal.

Gotten 6 calls, none of which have I answered.  They hang up and don't leave a message.  This has occured only since putting my number in a local newpaper for a dog I am re-homing which includes an online ad as well.  The ad was free...evidently I didn't read the fine print in the agreement.  Thinking that's how they got my number and why they think they can call me.

Even the do not call registry does not stop Robocalls. These people are so annoying. Why is this legal?

got 3 calls from this # today, no messages. i never pick up unknown numbers, especially if they are blocked. this type of thing has happened before and i think it's awesome that sites like this exist to help figure out such mysteries. thanks, everybody :)

Have been getting calls from this # at least once daily, today 3 times that I know.  I never answer.
