I got this while I was in school on 12/20/2018. I saved it in my Dropbox and forgot it until tonight. It might be dead, but I'm still posting it here in case it is still going. The link to the voicemail is below:
The phone number: (908) 505-0945
Have fun with these guys.
P.S.: I'm not going to call them back. What are they gonna do; arrest me? :D
