“Complete Savings” Scam

I woke up this morning and checked my bank account and saw €15 was gone to “WLY*COMPLETESAVE.I”. I googled this and apparently it’s some “online shopping money saving” subscription website that I have never signed up to? After reading about it on Trustpilot the same thing happened to other people after ticking a box to get extra savings when ordering on sites like Dominos and Debenhams - complete scam getting customer’s bank details through a third party. I managed to cancel my subscription (that I never subscribed to) on their scammy ass looking website and I clicked on a button to get a refund but god knows will I actually get it or not. Just wondering if this has happened to anyone else and also a warning to check your bank accounts for a dodgy transaction that looks like this.
