Sorry about your broken figure. Their quality control and customer service within the US is just as terrible.
They could be the coolest toy company ever with their great ideas and explorations into lesser known parts of the franchise. But their attitude and refusal to listen to any constructive criticism or take any accountability for widespread issues made me quit years back.
Just got sick of shoddy paint jobs, warped plastic, and figures breaking right after opening. Say what you will about Eaglemoss, the times one has been broken they shipped out a replacement for me the next day, no questions asked.
Japanese figures such as Kotobukiya, SH MonsterArts, Figma, and Medicom have been fantastic. Haven't looked back.
Honestly I wish the 7" scale affordable figures would go back to McFarlane. They've really been making a comeback as of late, with really nice 7" figures. Maybe even Diamond Select as they're already doing some Alien products and have involvement with Disney through Marvel figures.
NECA has held the mainstream figure license for long enough. Time for something new.
Anyway, I'll get off my soap box. I'd recommend getting from Big Bad Toy Store, they're great, and I believe they ship to the UK. Yeah shipping can be rough but you can bundle items to make it cheaper with their
'Pile of Loot' feature. I think eBay also has buyer protection, you could try contacting their CS.
