First off, you are WAY out of the loop, and completely uneducated how eBay works. Did you bother to read the TOS? I can tell from your rant, you haven't.
You are free to complain to anyone you want to, but it's going to do you NO good except to further tick you off. This issue boils down to YOU not understanding the platform, OR your duties as a seller. ANY platform you sell on is going to expect you to perform certain duties, and give a certain level of customer service. If you are not willing to conform to the platform's TOS, then you better just plan on having a big ol' yard sale. As buyers, EVERYONE expects certain levels of protection. Like you have just learned, your duties as a seller do NOT end when you hand off the package to the carrier. Like it or not, that's how it works on ALL platforms. Like it or not, ALL CC companies give consumers protection. Like it or not, processors like PayPal, give consumers protections.
So if you can't deal with that, you are better off avoiding ANY online platform and moving to yard sales/flea markets and selling for cash only. Any time a CC is involved, the sale never is over at the point of sale. There is no "all sales final" on ANY sale involving a credit card, period.
