Renprop agent Algis Drabavicius bad attitude

Renprop agent Algis Drabavicius has very bad manners in talking to potential buyers. I've been speaking with him the whole week about 2 properties I saw under his portfolio. This morning he calls me but I was in a meeting and so my fone was off. I call him immediately 5 minutes later and he answers with an attitude, saying I'm avoiding him. Before I could explain that I was in a meeting, he then shouts at me as if I was his child or something then drops the fone on my ear.

Firstly we've never met in person and he doesn't know me to to talk like that. Secondly if this is how Renprop agents deal with clients, I want nothing to do with them ever. I've been dealing with different estate agents in the past, I have a number of properties and won't tolerate stinking attitude. People who have no etiquette and respect towards others.
