Please don't call this #

I received several calls throughout the day from 877-626-4125 they finally left a voice message yesterday 11-25-13 at 12:19PM, it's from Liberty Mutual Insurance. They stated that I filled out a request for information online.  I am satisfied with my current insurance company, I did NOT fill out anything online pertaining to getting information about new insurance.

Today 11-26-13 at 09:51 I received another call from 877-626-4125 during working hours, this time they did not leave a voice message.  I don't know how they got my number, the next step is to block their number as I noticed others have done!

I've been answering the calls and they seem to be from all sorts of insurance companies.  Liberty Mutual was one of them. I did not recognize the company name of another caller.

SCAM ALERT!
I also did an online free car insurance quote early this morning.  I thought I was filling it out only for Farmers Insurance, but after I entered all my info I turned out to be a scammy page.  :(
About 2 hours after filling out the "free auto quote" I was in a meeting this morning for 50 minutes and missed SEVEN calls! No voicemails.

1) Unknown Number
2) 8776264125
3) 5754461435
4) 5754461434 (twice)
5) 5754461419 (twice)

I did a online free car insurance quote and they started calling once every hour but they don't leave a meassage I finally had to block them.

They just called, I answered but they never said who they were, and asked for a name I have never heard. This was the last of 3 calls I got within 5 minutes. The other two numbers were (in order) (201)645-5700 and (908) 279-0720.

No message on my cellphone either
