Who called from 3055331081

We missed a call from this number.

I received a call from this number from a "Diane" who claimed to be a judge's Judicial Assistant telling me that I was supposed to be there for a hearing.   She either hung up or dropped the call, but did not call back or answer our calls back.  Nor was there voicemail.  She didn't leave the case name or the right case number.

I keep getting phone calls from this number. recd. 6 within 30 minutes
Caller ID says  MIAMI DADE  CO J
I get a series of beeps when I answer

This number called me twice but i did not answer b/c i did not know who it was from.  they did not leave a message nor did i return the call.

number just called me.... I called back and it says "we're sorry.... this number could not be competed as dialed"
