The quick way to handle this is to tell them you sold the car. Also, if you get calls about your computer needing to be "fixed" remotely, just tell them you don't have a computer. Works for me!
I keep getting calls from NATAD as well. 3+ a day and never says anything when I answered. Called the number back today and got the voicemail of a guy in atlanta, GA. He actually called me back and had no clue why I was getting calls from his number. especially since it was the number that is only used by his work laptop. So, good luck finding a solution to this one.
They called and told me I was the owner of a 2006 KIA Sorento but could not tell me any thing else! They only said they were calling to check on the car I just purchased! I didn't purchase any car! They said yheyvwere the warranty company and I was either the owner or co- owner of the vechicle! I don't know what that was about. I know I have not purchased wheels lately!
