Calling with threating message and leave the number 855 228 7515 and threating to freeze my accounts and my job

Same thing. Pre-recorded threat

The guy told me I was going to get served in 4 8 hr and good luck and hung up on me when I would not confirm my social security number with him. Called him back and he asked if I was going to start harassing him at his job now.  I asked to speak witha manager and he told me no. Asked if I was going to pay my bills and asked if I was going to pay a hospital bill that he has in his possession I hung up on him. Very rude! !!!
