VAT charges on Evri postage labels purchased through Amazon

Not sure if any of you can help with this, but I am trying to claim back the VAT Amazon are charging on top of Evri postage labels (which already include VAT), as I’m VAT exempt. 

For starters, I’m under the impression that this not actually legal, but either way, I contacted Amazon to this effect in April last year, and was eventually refunded all of the VAT they had charged me up to that point.I’m now being told that this is not possible now due to some regulation that came in in August 2024 – though it sounds like this pertains to Amazon fees (not third-party postage)

For selling accounts with business established in countries in which AEU has a branch (UK, Germany, France, Italy, Spain, Netherlands, Poland, Belgium, and Sweden), you will be invoiced by your local AEU branch from August 1, 2024. As a result, local VAT rules will be applied to Amazon fees, "where required by law". This is an universal change that is applied to all sellers irrespective of VAT registered/unregistered status or previous exempt status.

Any ideas? I’m getting a “computer says no” approach from Seller Support! 

Thanks a lot...
