In the threads I usually scan in any forum, the response in a case like this is always to do something severe like to hang the seller by his thumbs and have a large cannibal choose his favorite cuts... Where have you read a thread proclaiming the seller is always right?
Admittedly, almost any debates about feedback gets swamped with messages from the poor sellers that need to reserve their feedback for retaliation against unsatisfied customers, but other than that, I have not seen a leaning toward supporting the seller.
At any rate, you did not get what you wanted, after asking the proper clarifying question, and the seller is not willing to make it right. You are obviously not responsible for his misinformation. He could have answered "I don't know" very easily.
I know the conversion to 10 speed can get expensive, so changing your whole group isn't an option... but I wonder if someone makes wider spacers to use 9 of the 10 cogs in a 10 speed cassette... This seems like a potentially inexpensive approach.
If I recall correctly the ridges on the freehub are higher on a 10 speed requiring deeper notches in the cogs and spacers, and since all spacers do is hold the cogs apart, I would consider using the spacers from a 9 speed cassette and filing them to fit onto a 10 speed freehub (if this would indeed give the proper spacing.
Good luck however you choose to approach this.
