Scary they got through without you authorising though.
I've found:
Nationwide (bank not credit) trigger happy on blocking card which can be a pain sometimes buy saved me this time.
My asda credit card I've been caught before and had to claim it back which wasn't fun and lots of hoops to jump through.
I'd tell you how my marks and spencers credit card was buy I don't use the bloody thing. The android app refuses to run as I have a FOSS keyboard so never bothered to even put the thing in my wallet and register it.
