Because this is an unprecedented situation? If you would rather do it that way, good for you. Others may not have a warm and fuzzy with how David's is handling the situation.I don't understand why some owners/renters want to talk to the other party so badly. Why did you go through David's if you want to deal directly?
I'd rather go through the rental company and be contacted that way - that's why I used them.
Edit: Additionally, for some people like myself, it is their first time renting. If it is your first time why wouldn't you go through David's? It makes perfect sense, does it not? However, we all got slapped in the face with this and are trying to navigate it.
