There are several MSC's who do these -- I've been asked by 3 companies, and thanks to people like Cettie who post the hazards, I declined.
I did do several life insurance shops, and wanted to kill the pesky agents who would call my office phone 10 times a day, and each time scream into the phone my entire personal information.
Yup, 10 times a day, for weeks, the worse one screamed ...
Is So and So there??? Pause, "She's, age X, at (home address), non-smoker, who wanted 100K insurance. Tell her to call --- blah, blah, blah"
Thankfully my husband has a great sense of humor....'cause it was a horrible month. -- All for $10 or something equally stupid.
On the car insurance -- two out of three MSC's clearly stated they pull your credit --( the 3rd called me on the phone.)
Don't mess with your insurance, and don't mess your credit -- Thanks my advise in shopping and in life.
