Really poor service

Anyway I asked a simple question of Yieldkit for this (Does someone get paid for each click or for each purchase made) with this person being fully confused of a simple question resulting in me giving up and to be honest I amazed by how many people offer incredibly poor support for wordpress plugins which I find weather I am looking for a incredibly simple or hard to find out plugin the service of majority of them are very poor which does surprise me since to be fair most other businesses I Deal with give at least okay service.
