The phone number that is calling you is from a Teeth Whitening Company.  In most cases, if you went out to their website to sign up for their free trial, and cancelled out once you realized they were trying to sign you up for automatic deliveries, they kept your phone number and are now trying to call you with the offer.  They called me quite a bit yesterday and then 5 times by 9:30 this morning.  I finally answered and it was a woman speaking broken English, and sure enough, that's who it was.  I told them I was not interested, take me off their call list, and they still called after that.  

Make sure your phone number is registered with the National Do Not Call Registry.  https://www.donotcall.gov/default.aspx  It states that a business can call you if you have had prior dealings with them, however, if you have asked them to put you on their do not call list, or not to call your number any more, then they are no longer allowed to call you.  If they do, then you can file a complaint (which I have done).  Here is information once your complaint is filed...

Do not call complaints will be entered into a secure online database available to civil and criminal law enforcement agencies. While the FTC does not resolve individual consumer problems, your complaint will help the agency investigate the company, and could lead to law enforcement action.

Also, I have contacted Level 3 Communications, which appears to be the service provider for their phone line.  I've asked them to look into the way this company is handling their business practice.  

I have also sent an email to the Attorney General with complaints. I did get a response already and was advised to go to the Do Not Call website and file a complaint.  If the FTC gets enough complaints they will investigate the company.  

There are actually several threads about this same phone number going on.  If you go to Google and just search the phone number, you'll see there are a lot of people having this issue with this company.

BTW, I'm from MD.

Hi Joyce,I did wind up filing a complaint on the NDNC registry yesterday.So far today no more calls.I did start to fill out the form for the teeth whitening system but cancelled it once I realized they wanted a credit card number.I figured this was safe because SUPPOSEDLY a woman from my home town discovered the "secret" but I don't have a credit card.At any rate I have been left alone so far so maybe they got the hint.I will continue to monitor the situation.Thanks for the information and I hope this resolves the problems others are having with this company.

This is pure harassment.  I have not called them, they call CONSTANTLY even though I used there DO NOT CALL LIST.
They just keep calling and calling.

I WANT THEIR ADDRESS. I WANT TO VISIT THEM.

These people need to be SUED!! or Worst.

I received calls yesterday & today. Finally, I spoke with a live person. I don't even know where she said she was from, but I asked to be removed from the list. I figured if it was that important, they would have left a message the first time they called.
