1. Sounds like an ebay sale, not a Fatcogs sale. You weren't a member here, and only signed up to air your drama, which you've done under the General Fat Chance discussion. It has nothing to to with Fat Chance, or Fatcogs, and this thread doesn't belong here.
2. Individual people selling on eBay are not retail stores with dedicated sales staff to cater to your every need. They are usually people with busy lives clearing out old stuff, as they can find a minute to do so. If you bought a Titus full suspension frame set for under $200, that's beyond a steal. You're not going to get handholding and the champagne room treatment for that price. If you want the sale to go smoothly, you pay the money, don't pester the seller, wait patiently for as long as it takes, and be appreciative when a $3000 frame shows up on your doorstep for $200. Someone paid a LOT of money to buy you that bike. Just thank them when it shows up at all. If you're impatient or need numerous emails answered, go to a store, and pay retail. That's what you're paying for.
3. This is a private matter for you and your seller to resolve. If you're going to make a big public stink against a respected collector, you'd better: 1, have very valid complaints and 2,not be a basketcase about it. Sellers are already on the losing end of every ebay transaction by ebays own design, to attract buyers, and doubly so when they refund you and cancel a sale. They still get socked with a pile of fees and have wasted time and still have to sell the thing they spent the last 3 weeks trying to sell on the bloody site. You're not out anything but your expectation of getting something for nothing. This is why by the end of one of these transactions, if the seller is a human being with human emotions, who already has enough issues popping up in their life, they will rather throw the frame in the recycling bin than deal with it or you the troubled buyer, for another minute, and certainly have no interest in rewarding you with it, after all that.
If ebay were not disproportionately stacked against sellers, there would be less of these issues and animosity overall.
