Oh dear sounds like a right pain for you.

I take it that the 130 Euros compensation is just off another room booking with med hotels and they are not going to give you a cheque as compensation for all the phone calls and uncertainity ?
Maybe you could write back saying that you would prefer it as cash as it is to cover the fact that you were out of pocket calling the UK trying to sort it whilst there & the worry for 4 days of not knowing if your accommodation was going to have to be paid a second time?
It's got to be worth a try as the worse they can do is say no, but if they are worried about repeat bookings and their reputation which they might be in the current climate, they may change their mind and send the cheque instead.
