After several contradictions about whether I will receive a refund for the returned items, finally they tell me that they will not proceed with the refund.

What was their exact reply?

I have received many responses (contradictory as to whether or not I was going to receive the refund, and when I was going to receive it).  But the definitive one is the one that indicates that it asks me for payment.

^ This holds no grounds If the claim was declined for all the wrong reasons.

You first need to establish why It was declined, and whether or not the decision Is justified.

They only see that I have been reimbursed by mistake and that I owe money them

To them and everyone Involved, you're not an SE'er, but rather a legit customer who simply filed a claim.

Today I am a legitimate buyer, but tomorrow if something goes wrong again it would be a lot of coincidence to continue being someone legitimate.

On the other hand, in your years of experience, have you seen a case like this in Zalando?

Do you think they will keep their word and go to court?
