The trick to this is to answer the phone, sound like you're interested in their product, get them to send you something, anything, with their name on it, and then you will kow who they are. you can sue them in small claims court for the federal penalty, I did it twice with unsolicited faxes and got $500 each time.
I amnswered the phone and asked the person on the other line I said "please put me on your do not call list"
and before i was done they hung up in my ear. Every damn day I get automated phone calls from this Insurance company.
I have repeatedly told them to stop calling me, and advised them that i am on the do-not-call list. when i asked for the name of the business and the address (the information i need to file a complaint with the attorney general) they hung up on me. I have seen forum after forum about this number, but nobody can find out the business or the address.
These people will not stop calling me, and on my cell phone no less. I would love to have their individual cell numbers so I could return the favor and waste their air time.
