Spaceagency interview questions

I flew to the UK just for this interview all expenses paid by me, it was a normal interview I didn't got accepted and that's ok, it happens. But I would have appreciated to have some sort of follow up after many emails responding to Sarah and extending my stay to accommodate a change of schedule from her. After the interview, she just stopped replying. Some basic manners for closing the process would have sufficed instead of having me wait and spend money for nothing.
