eBay has rules about what can and can't be mentioned when leaving feedback. How can we know why your feedback was removed unless you tell us what you said?
You don't leave many negs, but the last one you left a few months ago would also have been removed if the seller had reported it. You are not allowed to mention eBay being involved in getting your money back.
You are also not allowed to reproduce correspondence with a seller, so the neg you left over a year ago could probably have been removed too.
We are seeing more and more feedbacks being removed. This started when eBay removed the limit on the length of comments. Many buyers now ramble on, heaping one complaint after another on the seller. Most don't have any idea about eBay's rules on feedback, so the longer they rant the more likely it is that they will say something which entitles the seller to have it removed.
