8005529841

this number called when I was not home, but they did not leave any message.

They have been calling from this number for weeks. I don't answer and am on the DNC List.  But today they called EIGHT TIMES from 9am-Noon!!!!!!!  This is RIDICULOUS!  Frustrating to say the least.

I received a call today from (800) 552-9841  but did not answer.   No message.  Typically, if I receive a call from an unrecognized number, I don’t answer, but Google it.  If there is a history of abuse, this is what I do.

I file a complaint with the FCC against this caller at http://www.fcc.gov/complaints.  I get an acknowledgement after I submit the complaint, and, after a while, the FCC will send me a formal email acknowledging my complaint, assign a complaint number, and advise that it is investigating the complaint.

At a minimum, a complaint should be filed with the FCC at http://www.fcc.gov/complaints.  The form only takes a few minutes to fill out and you can file a complaint against three different numbers.  I think this is the most effective way to deal with this problem.  If you file a complaint with the FCC, be sure to submit the link to this thread in the complaint form.  That way, the FCC will be aware that the caller has done this repeatedly.

This is a copy of an email I received from the FCC acknowledging each of my prior complaints.  It might take a few weeks to receive the acknowledgment, but you should get one:
“Dear Consumer:
Re: Case # 12- XXXXXXXX
Thank you for contacting the FCC regarding possible violations of the Telephone Consumer Protection Act (“TCPA”) and the Commission’s telemarketing and junk fax rules.  Information provided in consumer complaints like yours helps the Commission to combat abusive or unlawful practices in these areas, including taking enforcement actions against individuals or companies.  In this regard, the Communications Act authorizes the Commission to issue citations and, in some cases, impose substantial fines upon entities that violate telemarketing and junk fax rules.
Although the Commission does not resolve individual complaints, each complaint is individually analyzed and assists us in enforcement actions to protect consumers like yourself.  You should be aware that the TCPA also provides for enforcement of the telemarketing and junk fax rules by state attorneys general and by individual consumers.  With respect to the latter, the TCPA permits individuals who have received certain unlawful telemarketing, such as junk faxes or telemarketing calls, to sue the violator in state courts where they may be awarded up to $1500 for each violation.
We invite you to visit the FCC’s Consumer & Governmental Affairs Bureau’s Internet web site at http://www.fcc.gov/cgb for more information.  You may also call the FCC’s Consumer Center toll free at 1-888-CALL-FCC [1-888-225-5322], TTY: 1-888-TELL-FCC [1-888-835-5322].  
Sincerely,
Sharon C. Bowers, Division Chief
Consumer Inquiries & Complaints Division
Consumer & Governmental Affairs Bureau“
Please invest the small amount of time necessary to file the complaint, particularly if you are irritated by these obtrusive and incessant calls.  Good luck!

Called on the landline. Didn't identify as a person or company. Don't have this number in my phone book. Nor did I call any company for service that would require a call-back. My phone is on DoNotCall list. Can see how well that works!

I recieve calls from here all the time. They never leave a message, caller id just shows up with the number unknown name. Annoying, and I too am on the do not call list.
