I’m sort of surprised by this. I have bought two DACs from Metrum and they have always been unbelievably responsive and accommodating. In one case, I was going to be traveling a few days later and so instructed them not to ship until I returned. Instead they offered to overnight the DAC from Netherlands to US so I could have it before my trip. I also requested a return/refund on the other DAC and that was processed promptly.
