Return to china- any point?

[wobblyweewoman]

I fell for an Instagram ad, I should have known better, 2 beautiful suits for 70 from a London based retailer
They arrived and they're terrible and the retailer is actually in China.
They replied to my email seeking a return offering me 15 % but I refused saying I want a full refund.
I've packaged it up to send to China which I think will cost 20/30.
Am I doing the right thing? Will I get my money back,?
Or am I throwing good money after bad?

You are possibly spending £30 to potentially gain £40 back?! What’s the point… accept the 15%, learn the lesson and move on.

Not sure how someone could make two suits for £70 in the UK.
