The best restaurants serving Vietnamese food in North East Scotland

Ordered on Christmas Eve from Saigon Restaurant, to collect. Arrived at the specified collection time and the restaurant was closed down, in darkness. Phone number had been disconnected. I have been trying since to get a refund from Just Eat but all they say is “take it up with the restaurant” as it was an order for collection. I explained that the restaurant no longer exists, but they don’t want to know. Seriously disappointing
