They keep calling my cell. I'd like to share a trick I use to avoid these types of calls:
1. Get a Google Voice phone number
2. Configure your cell phone to forward calls to the Google Voice number if not answered. Do not use the phone companies voicemail
3. When a call comes in, if you don't recognize the calling number, don't answer. Some phones will allow you to immediately reject.
4. The call will get forwarded to Google Voice. If it's a real person, they will leave a message. If it isn't, and most of these types of calls are automated, no message will be left.
Ever since I started doing this, I don't get bothered. They call, but I don't care
