You're welcome

Can you please advise.  How to do it right?  Just send an email to them in the usual way?

Just send an email to them in the usual way?

^ That Is correct.

Specifically request your claim be escalated and reviewed, by a team member on a higher level who was not Involved In the original decision.

Friends, this is some kind of laugh. The issue price is only 800 euros. My acquaintances worked with larger sums, but Zalando seems to be mocking me.
I did everything as previously discussed. And I was told to wait for an answer to the mail. As a result, no one wrote to me for several days, and when I wrote back, they told me that the decision would not be changed, we apologize for the inconvenience.
