I am getting an ever increasing amount of telemarketing old calls on my cell phone. I am and have been registered on the national do not call list for years, but it does not matter. Is there anything that can be done to decrease this short of changing my number? My business runs through this number so that is not really a feasible thing to do. Yesterday, as an example, I got 4 calls from AT&T trying to sign me up. Today, AT&T has already called once.

Cold calls is a sure fired way to ensure that I will NEVER sign up for services. If you are a scammer, you will get nothing as I said, I will never sign up for anything through cold calls, EVER!!!
