Number has called my cell a couple time a day this week. There is no sound on the other end then a hang up. I finally dialed number back. A male recorded voice says "the survey that we called you about is now over. Please press 9 if you would like to be removed and not receive future calls". I just hung up will try to use my block feature on phone to block them out. If the survey just ended why did I just receive a call a second prior? Someone need to seriously do something about this invasion! The phone company needs to make an over needed adjustment to the system with how calls are sent and received! We should be able to have an unlimited amount of numbers we can "block" without the phone company charging us for this service, since they are the ones who in fact are letting this scam occur! Just this week alone, my cell phone has all of a sudden started receiving 10-15 unknown caller calls a day! I am sick of it! I think it's time for a class action lawsuit against the phone companies and anyone else who is letting the ball slip on this! ENOUGH!
