Could you clarify- did you just get charged a customs fee, or is it/also because he failed to put put the correct postage on the item?
Most of what's gone on there would annoy me, but isn't a big problem with the trader in my opinion.
Customs- I don't know the rules for this and I wouldn't expect foreigners to be aware of the rules, or changes to them. Do you know how much the item has to be worth to incur charges? I know I don't, nor is it very easy info to find. Did he declare it as a gift? In any case setting a real value for the items
is the correct thing to do- if that causes problems, then it's a problem with the rules, not he sender.
Regards his holding back on posting on good traders- he's just following the eBay standard (though it might have changed recently) and you do need to recognise that alot of people get problems throughout that process. He could still have mentioned your sending stuff out correctly though (after all it's a editable post) but for convenience most people would probably wait until it's all finished.
Regards sending things after receiving theirs- when I did my 1st 2 trades on here with old well-regarded members [ooo-err Missus?] I offered to arrange things that way around. Was a bit rude of them to accept- but sensible.
What would I do? Check the customs charging rules 1st. Maybe post an annoyed thread of TacComms to release the tension and get 2nd opinions before thinking about naming him- that's a good idea
I do sympathise by-the-way, just think you're a little too annoyed at the smaller issues, cos of the bigger- that customs charge.
