We were 'got' a few years ago. We know where it was done and by whom but, although the bank confirmed fraud, stopped cards, sorted out accounts etc, we didn't find out what happened.
The only thing that did happen was a policeman asked us for details, refused to confirm/deny it was part of an ongoing anything, thanked us and that was that!
When my card was 'tried out' in Carphone Warehouse, the bank phoned me, I refused to talk to them and phoned them back on another phone. They asked me to check if I had my card - which I did I had used it to find out what number to ring and was sat at home, 20 miles from the nearest CW shop - they thanked me and that was that.
I don't think you do anything. Just follow the bank's advice, if you need a cash advance ask them, they are pretty good at sorting stuff like that.
Good luck, I hope the process is painless for you.
