Please don't do anything that you might regret. Think carefully about pressing for a refund. It might be a lot easier to just go with the flow and just wait for them to arrive. Say you did get a refund: what then? Could you find something else for the same price that could satisfy the hole that the Devialet left? Probably not, I'd say.
Edit: I think our posts may have crossed. I didn't realise you had a 250.
