I have no idea who the caller is because they never leave a message, but they call me nearly every day between 5 am and 8 am. I live in Az but I have a Michigan area code on my cell phone. They obviously have no idea who they are calling because they would realize the time zone difference if they knew me. I wish I didn't need to have a phone because calls like this make me want to not have a phone.If I didn't have a kid I would not own a phone. I am just plain tired of all the unwanted calls.
