I got a weird call on my magicJack?

This guy was threatening to blow up my house. He said somethings like "this is about the fourth call youve made today" and some filled with alot of swears like "Hear this F*CK YOU" and "Hey your momma still has worms crawling up her p*ssy" and many others. I found his name. He is Frank Garrett and he works for a compony called Duncan Construction. Should i contact magicJack? Should the police get involved too?
