I won an auction June 3 for a set of SSI 1.7/1.8 heat exchangers. I never received them and get no replies back from this seller. After winning and paying for the items two more people have posted negative feedback for him because they paid and never received items either. Had these negative feedbacks been given before the sale date I never would have bid on these exchangers. In over 300 transactions I've never been stiffed before on Ebay. Hopefully Ebay's Buyer Protection will refund my hard earned cash in full. It's up to a 30 day process from the time a case opens for a decision to be made by Ebay. This has really left a bad taste in my mouth.
