Is it worth it? Perhaps. Will anything happen if you don't? Definitely not. The only way for them to know there are issues is if everyone who has an issue reports it. If you don't report it and only come here in the forums to report it there is nothing that will happen. Tricia can't just tell them that there is a problem and how many people should be getting a credit and they will send it to her. If you are reporting them there is actual data to show them about a survey and they can either fix it or issue credits for it.
