its a scam his name or his fake name is jack spring and he leaves threatening messages about harassing at work/home yada yada if you call the police they just delete that number and buy a new one

This number 1-904-900-8450 is calling and threatening my job and to break my legs..called my mom a [***] [***]..This man called himself Johnny foster..And even made death threats..

Called me several times making sexual comments that were very offensive to me and to my husband.  Hung up on him and he kept calling me back, this guy also said his name is Jonny Foster and has a very thick accent.

Got a call from this number who indicated he was expecting payment from US CashAdvance.  When I questioned the validity of the charge he became biligerant and indicated he would have me arrested by tomorrow.  I've contacted the local police departments here with this information.  The person spoke with a thick heavy accent which at times was hard to understand.  I asked for clarity on his message but he became increasing irate and ended up hanging up on me.
