Scoopon refund (Peninsula Nelson Bay)

This is the second time that I'm about to get a refund from scoopon, currently they're rejecting the refund.
Just writing before I go to the fair trading to see if anyone else has similar issue.

It's the peninsula nelson bay which I have called since January (Expires 2nd March) and they never had weekend bookings. As of today, after making more than 10 phone calls to the resort, and 3 emails to scoopon customer service, they now don't have any room available what so ever. They said I can downgrade to a motel room or pay additional $75 but I want the room which I have purchased, but they don't have it. Now not even weekdays. My voucher is still valid but they don't have any room to provide a service and they are not willing to put me to any other dates which is ridiculous. I can't use my valid voucher which hasn't even expired yet!!!

And few weeks ago, when I initially seeked for a solution through scoopon, they had system upgrade issue so my initial request was received but I didn't get their reply. (This issue was officially announced on scoopon website which I found out two weeks later). So I've sent another email again asking for an answer and they copy and pasted the previous email that they wrote to me, saying they have some upgrade rooms available, but it was way too late. So scoopon's system issue now made it impossible to get a booking. (If many people are affected by their system issue, it's more like a ACCC issue isn't it?)

Both scoopon and the resort have disappointed me to the extreme, I have given them few options to put me towards the off peak season, and they've rejected it. Seems like they're trying to avoid people redeeming vouchers, because back in January, they did have weekend rooms available but as soon as I mentioned the word "scoopon", they said they don't have any rooms left. They emphasised that scoopon customers must use the room advertised, but ironically they're now providing a downgraded motel room which is not part of the deal.

Anyway, I'll be going to the fair trading (and apply a chargeback to my bank in the meantime) unless I get an immediate refund but did anyone else have issue like I did?
