I'm such an idiot - I've fallen for a scam having seen a sponsored post on FB advertising a half price Lego rollercoaster. Went and ordered it without even registering that the lookalike Lego site linked to wasn't legit. It was an early morning impulse buy and I didn't want to miss the opportunity.
Had an email saying that the payment had been approved. Didn't look closely til much later yesterday when I noticed info about the debit from my account would be more, and it was only then that the alarm bells started to ring.
Anyway, the 'bargain' price of £153 is actually £221 and the site has now disappeared. I've reported my idiocy to my bank but as the payment is pending they say they can't dispute it until it's taken. Don't understand why it can't just be stopped but there we are.
Please don't be fucking stupid as me. I'm sure nobody will.
