I bought a cashmere sweater from an ebay seller 8 days ago and paid as soon as I won. I emailed her 2 days ago to see when she would be shipping the sweater, but she has not responded. I do not understand some of these sellers. I always email and thank my buyers as soon as they pay and then ship the same day. Since she has not responded to me I contacted ebay CS this morning. I cannot believe what the cs rep told me to do. She told me I should leave her negative feedback right now so other buyers will know she is a bad seller, but I do not want to do that. I really want this cashmere sweater and I have not received it yet. Should I open a dispute now or wait another day?
