How to buy Minecraft on a pc?

[TowerRingInferno]

Ds has been trying to buy Minecraft from the Microsoft store for his laptop but has been unable to do so. It doesn’t like my credit or debit card.

When I google it this seems to be a common problem but I can’t find any solution online.

I’m clueless with things like this and wondered if anyone had come across this or found a way round it.
