Wow, in that case WOA has found a great business model for making free money.
I will try writing them with their "contact us" form, there must be a way.
Well, it has been communicated largely last year, that REFUND is possiblie, until a certain date!
Since you talk about LAST year (not 2019!), it's obvious, that this date has longst been expired!
You can however always try, that's for free. But I need to remind you, that W:O:A has outplaced the payment system of last year to a third party. ( and I don't know its name anymore, you should be able to find this in the NEWS section on top! (The English part as well) )
