Extremely Threatening Estste Agent

I saw a house advertised by Jacques Groenewald of Meridian Realty on Property 24 with an over inflated price and queried the price. He then sent me a threatening message on WhatsApp and said that he has taken the matter legal. Just for querying the price of an over inflated house. He was rude and unprofessional towards a possible client and put his company in bad disrepute with the public.
