This is about Patreon's own customer support (not any indiviudual creator on it).
Don't even bother trying to contact them. They take a shameful long time to reply and once they do, it's all standard emails. You clearly notice they don't take time reading what you actually wrote or asked about and just copy paste standard replies which often don't even match your problem. Or link to their "helpdesk articles" which also don't answer your questions.
Especially about VAT, even if you can proof you already paid it, they just tell you to wait till you can do your tax return to get it MAYBE back. Even though they don't have their codes in order.
So it's an absolute shame but to avoid wasting double taxing, frustration, and bad customer support, it's best to not get any physical rewards because if something goes wrong, don't bother hoping that they will help you.
