Unfortunately if you have had an established relationship whether it be for an inquiry or you had done business with them at one time or another, the Do Not Call list will not help you. You have to tell them to stop calling, and then they need about 30 days to have you removed from when you tell them to stop. FCC won't even help you unless it's been over 30 days for sure.
Called cell phone...left no message....calling from San Antonio...I block and they call back on another #...will continue to block all calls. I accept no # I do not recognize. Scam
