Calling about debt. I've paid my 2 online loans. Calling my job and family homes to threaten to sue. Not paying anyone because I paid my loan. Is this a scam or what?

I received a call from this number to inform me that they are trying to collect a debt, and when I requested to not call this number, any questions put in writing...she was rude and left a voice message on the office main line.

some lady called my job asking for me saying it was stp management is this a scam never heard of these people

Claimed owed the money. Scam very rude on the phone.  When asked to speek to supervisor she hung up on me
