Hmm, I at least received a refund on the tablet; I think half of it was paid out and half of it I opted to use as payment for Sailfish X.

An email I have stored from July 4th 2017 mentions "the tablet refund tool", so there seems to have been a concrete system for this refunding process as well. I abstractly remember something like that, though I must say my memory is shoddy and should not be trusted.
