This explains why they refused to accept an RMA for a motherboard with clearly broken capacitors. Eventually I took them to court, and they settled a couple of weeks before the hearing. Then they closed my account with no reason given.
One could ask why I would still want to deal with such a godawful company. Answer: they're cheap. So I looked up all of their directors' names on LinkedIn and guessed at their email addresses based on the format they use, and copied them all in my communications asking what they thought they were playing at. My account was reopened a few minutes later.
I don't think I've ordered anything since.
