You have quite a dilemma!
I don't know what NATS thinking is on interviewees pulling out at the last moment - it is possible that they may not look too kindly on an another application from you in a year or so; other Ppruners may be better qualified to give advice on this. I do know that some organisations, particularly airlines, only grant applicants one chance, if you turn them down once you don't get a second chance!
Far be it for me to suggest something dishonest - but there is a lot of flu' about lately- wink wink.
I expect you have used modern 'text speak' English in your post, but for applications etc it must be faultless ie capital I, there and their used correctly.
Best of luck!
