That is typical.
I had an account for a long time as both seller and buyer with one negative comment in over 300 from a person whose money I refunded when they said the item did not work (immediately).
My account was hacked after not using it for almost a year by some kid in Spain selling a non-existent $9,000 jetski. I cancelled the auction but not before two people had wired money orders to Spain through Western Union for $5,000 deposits. Luckily, Western Union in Spain was onto him and did not transfer the money.
I learned of the fraudulent auction using my username when questions to buyers started to arrive. I immediately contacted ebay and all bidders to inform them of the fraud and did everything they said to do.
After doing all of that and contacting them numerous times they still suspended my account and I have not been back since. I felt their customer service was horrible and I spent hours trying to fix it. They did not even cancel the auction so I had to modify it so people would stop bidding on it. I did all the legwork and mailed it all to them and they did nothing but suspend my account.
Have not been back since and use amazon.com or yahoo shopping now.
The only non-positive feedback I've ever received was a neutral from a buyer not happy with the guitar she had bought. Just one problem, I hadn't sold a guitar. It was an error by a newbie who had left a feedback for me that was intended for another seller. Getting that corrected was like pulling teeth despite the buyer writing eBay several times confessing she had left the feedback for the wrong seller.
eBay cares about nothing but the money.
I debated for hours whether or not to give a negative rating, but in the end decided to give that seller some feedback to think about, so maybe he wouldn't treat another buyer the same way.
I gave positive feedback on other sellers where the package never arrived or the item was totally defective and useless, but the seller was not technically knowledgeable enough to know that, like a Collins mechanical filter with the resonators rattling around loose in the housing. I gave them all the benefit of the doubt except in the one case where pure laziness and indifference put useless junk on my doorstep.
