Who called from 3852826866

this caller starts early in the morning calling over and over all day. I never pick up, they leave no message.
these calls started a week ago

I must see if my phone has a rejection option

I got about 10 calls from 385-282-6866 on my cell phone number that I never give out.
about the 8th call they left a message address to Susan from Cindy to call back at 1 pm and be part of the conference call at 866-844-9417 pass code 7716908682. (Of course I am not Susan and don't know any Cindys)
When I look up this number - I landed on this:

"a Bidders Conference will be held on July 16, 2012 from 10 am to 12 pm at the National Grid facility located at 280 Melrose Street, Providence, RI 02907, in the Auditorium on the 3rd Floor. Dial in: 866-844-9417

I have no idea what this is.  It is all fake and a scam as far as I am concerned. Just wish they would stop calling.

further to my message of yesterday, I answered a called from 385-282-6866 the guy said hes was from an internet money making company and that iI had signed up for.  I told him that I have not signed up for anything of the sort.  He told me that I did and even gave them a credit card number.  I repeated that I have never signed up and have never given anyone my credit card number. Told him to stop calling and I hung up.
this is definately a scam of some kind.

This is a scam!! And if they are calling you, you need to check all of your credit cards. They have gotten your information and are making sure you are not on to them yet. They claim to be an Internet money making company. Yeah they make money on the Internet, by stealing your information and charging your cards. Small amounts I am guessing. Biggest charge I have seen is less than 10 bucks.

I get calls from this number everyday...it's starting to get me really upset.  They never leave a message.
