Hey there** **I have a major problem with buying an item on eBay, I have never experienced something like this before, here is my problem list:***. i have purchased this boots Salomon Men's Quest *D * more than ** times from * sellers, and after purchasing they are saying that item is not available, when I saw this behavior I started to send question to seller on items, i asked them if the item is really available in their inventory to buy it, even after they told me item i in their inventory after purchasing and losing several days they told me that item is not available. So, what doest it means?? ***. this reputable seller https:**www.ebay.com*usr*classyuinc acted like a jerk, they even not message me, canceled order without any message and at the end they blocked me, I'm very disappointed I feel very badly why i was blocked? is this how eBay works? if they cant ship item they must block me?***. i left negative feedback for https:**www.ebay.com*usr*classyuinc seller because they deserve it, but how i see my negative feedbacks (Feedbacks on canceled items) is not available on their page, there is only one feedback i left today but i left * feedbacks and they are not visible and their ranking is not changed (I've purchased boots * times from them), so my question here is how or why the feedbacks on canceled items is not visible? why are they removed?
