I had a pack go missing from a vendor who is currently under investigation on Nucleus. He offers 50% reship and he has messaged me saying that he can't refund me directly through the market until the investigation is resolved. I've never had to take a refund before and I'm wondering is it out of line for me to ask for the payment to be made outside of the marketplace?
You could ask but he probably won't do it. Obviously if vendor is scamming, he won't. But let's say he is legit. If he handles it outside of the market system, he'd have to trust you won't double dip and still pursue a claim via the market.
