I can't upload pictures when asked for them, I can't see previously sent messages. Please tell me I'm doing something wrong rather than the service being horribly designed.No option for uploading imagesNo sent?

With a case, all messaging is within the case. I had one recently and could see both sides of the conversation, so I'm not sure why you can't.
