According to dictionaries, A collection agency, also known as a debt collector, is a business that pursues payments of debts owed by individuals or businesses.
But I have seen in movies that criminal organizations ( Mafias) hire some obnoxious men as ( illegal) debt-collectors whose job is to collect the payments by force and violently, if necessary!
I'd like to know if there is any slang word, term , phrase or idiom among those Mafias members for calling these "debt-collectors" or not!
1-I have found a British English word "bumbailiff" but it refers to officers whose job was collecting debts,in the past; so I'm sure I cannot use it for those men hired by Mafias as debt-collectors!
2-In the duplicate question, Morteza is looking for the "debt-collector", but I am looking for its slang equivalent! So please open my question!
