I had an INRC opened and the very next day the buyer sent me a message saying it had now arrived and was more than happy. (The message was sent outside of the case.)
The trouble is RM clearly haven't scanned it, so it's not showing as delivered and the buyer hasn't closed the case. I sent them another message asking if they could kindly close the case, but I've only been met with radio silence. I replied to the case thanking them for confirming delivery, hoping they might see it and close the case but again nothing.
Do I refund them anyway? I know the case will close after a month but at any time before then they might escalate, and I'll get a ding on my account (which I want to avoid).
