I have successfully sued telemarketers in small claims 3 times for calling my home phone number which is on the do-not-call list. You must find out which mortgage refinance company they are calling for in your area. That will be the company that you sue. The law states that hiring a telemarketing company to make the calls is the same as their company doing the calling. In the last year I have collected $8500. from these idiots in the past 13 months. Most don't know that they're responsible for the call since they weren't actually the caller (they find out soon enough). Go for it; It's well worth it and a lot of fun.
I got a call from this number 5/31, left my name and number. It is a recorded message which I have heard often and opted out several times only to be called again. On 6/1 Neil Phillips called from 619-245-4943. He said he was with All State Law Firm. They call for loan modifications. Told him I was informing the A.G. office and he aaked why. As I was explaining why he hung up on me. I plan to call Neil often and everyone else should too at all times of the day and night.
