These companies might frustrate you guys by making multiple calls, but all they are doing is entering random phone numbers in a database and sending out calls. I realized this after I got my son a cell phone and saw the same phone number call his number, which was two days old, and my number. I had not given my son's number to anyone yet, so that told me that any of these companies are just entering a sling of random numbers in their database. If you respond, then they know that you are a valid person. Just ignore any call that you don't recognize and google the number, and if it isn't one you recognize, delete it. They use local area code to trick the person into thinking that someone local is calling. BBB isn't going to shut them down because they can just come up with another phone number. Just don't respond and don't ask to be removed. Just ignore and delete. My voicemail is deactivated for this reason, and therefore if someone I know needs to get in touch they text me.
