Refund not allowed?

I tried 3 times to request a refund for Diablo IV (I bought it and never installed as I realized it doesn’t work on Mac).
3 tickets that are marked “It needs a manual revision, please open a ticket”.
I can’t reply to the ticket and if I issue a new one I end up in the same place.
There isn’t a single email I can use, it only allows to use this automated system that clearly doesn’t work.

Order is EU838166804

Please help
Thanks

The Blizzard Refund Policy in English for EU is available here: https://www.blizzard.com/en-gb/legal/ed0dfa66-698e-4910-9f86-a142730298e4/blizzard-refund-policy – do review it if you haven’t yet.

If you think you meet the criteria for a refund, submit a ticket to Blizzard here: https://eu.battle.net/support/en/help/contact/1998/ticket

Good luck !
