Confusion about purchasing from the asset store UK

I’m trying to buy and download some character and animation assets and I’m running into an error when trying to use Paypal as I don’t have a credit card to use. I’ve been in touch with Unity and apparently it’s an issue with VPN or similar (that I don’t have) that means the transaction stays pending. I’m wondering how I’m supposed to get around this since I have no way to purchase download or use these assets otherwise?

I’m assuming that others from the UK may have had a similar issue when wanting to download assets as me as I am assuming that it might be an issue since the country is not separated from the EU??? I’d be grateful to know if anyone knows anything about this and how I should go about solving this issue? Many Thanks.
