They call all the time...one time I did answer and they asked if I was me. I said well who are you? They refused to tell me who they were...I said then dont call my damn number again...they still call.
I have received calls on my cell multiple time a day and once a day at work. They never leave a message to tell me who they are or why they are calling.
If they are someone legitimate then you would think they would leave a message about why they are calling.
