keeps calling and hanging up

Lady with very thick accent (very hard to understand) called asking for an employee (lots of background noise with others talking, sounded like same conversations taking place). Said she is calling from a legal office, but would not give name of company. Told her she would have to reach employee at home if this was a personal business call. She kept insisting that I take a message. Told her I would not. Ended call. Called so number back, no introduction or company name, a guy name Don answered.

Called cell didnt leave a message

similar to others...stated they know a legal claim that was against me.

Text me at 4:30 AM claiming "their government approved program can reduce back taxes"

He said late fees and I told him for what then he paused I ask him his name he said his name was david smart I can see it was a fake name from the information above...
