Got several calls threatening me saying they have two complaints against me and they are going to contact my place of employment.

Did she say her name is Jules brown and the call came from silver Springs? She called me several times threatening me.

I got a verbal message asking for "JERMAINE JOHNSON".......duh!!!!! $CAMMER.......
PRESS #9 in their ear......HA!

ID themselves as "Upkeep Consultancy", supposedly a "mediation firm".  Right.  The term "mediation firm" is scammer double talke for debt collector.  Told me they were in Miami, but have locations around the country.  This is the identical spiel the off-shore Caribbean scammers often use.     Lady has a curious accent.  Sounded Caribbean.   Pretty sure this is just another off-shore debt scamming operation.  Ignore and block these calls. I sent her to school  -- rather roughly.  Ignore and block any calls from this number.
