Calling someone a *****

So this morning i received a call from a company called DMC.I could not respond to the call as i was busy at the time and a voice message was left by the collector.

His voice message was as follows “ANOTHER DISHONEST *****”

How dare you call me a dishonest *****.I am definately taking further steps against DMC for slander and charactor defimation.

How many other people are there that has not come forward yet and conplained.
