No refund with iDEAL payment

On the 26th of June - while I was on holiday in Indonesia - I subscribed to a yearly Creative Cloud Pro plan and made the payment of € 921,15 immediately through iDEAL. This ‘iDEAL’ is the most common way of making online payments in my home country of the Netherlands and I was happy to see that I could use it with this purchase as well.

On the 30th of June, I received an email from Adobe that my subscription had been cancelled due to fraudulent activity being detected in relation to my account. So far I had only used the Photoshop Express app on my mobile as I was on holiday in Indonesia without a laptop with me. So I have no idea what this fraudulent activity is about and when I reached out to Adobe about it, I was told that they cannot share any details about it and that my subscription can not be re-activated. They did tell me I could use a different email address to create a new Adobe account, for which I could purchase a new subscription.

As my subscription could not be re-activated, I asked for a refund of the € 921,15 that I had already paid to Adobe. I was told that I had to reach out to my bank to raise a dispute and that the bank would eventually have the return my money. I did as they asked and called my bank. They told me that they can never refund anything that paid using iDEAL (with other payment methods it would be possible) and that the merchant should be the party refunding my money. From here there has been a lot of back and forth between me and Adobe as well as me and my bank. Adobe keeps insisting that the bank should make the refund, whereas my bank is saying this is simply not possible in any way. Information online is also very clear about it; all sources (including my bank’s website and iDEAL’s website) say it is technically impossible to refund iDEAL payment. I have shared this with Adobe multiple times now (including screenshot of the statements on the websites and confirmation from my bank / iDEAL by e-mail), but Adobe insists that they cannot return my money and that the bank should sort it out. They would only have to do the simpelst Google search to find out that what they are asking me to do is simply impossible. Why are they even allowing this payment method if there is no option to resolve something in case of a dispute?
 

I am highly frustrated with the situation as this feels like pure robbery. Adobe informed me that their decision is final and that the case is closed. I have now reached out to Adobe senior management (without any response so far) and I have also reported the situation to consumer protection authorities in The Netherlands. Do I really have to go as far as to take the legal path to get my money back?! There is absolutely no way Adobe will win this case if I take it to court.
