That's weird. I have 10,000 or more notes collected over a 2 year period. I have and use daily Evernote on my iphone, ipad, mac at home, and Windows at work. I have never lost a note, and the 2 or 3 times I have contacted customer support, they have responded immediately. I'm not doubting you have had a problem, it's just weird how your user experience is so different from mine.
