Double charge for same item

[LunaGhost]

Hi, just wondered if anyone else had this issue at all? I have no idea who or how to contact galaxy store to challenge this. I bought one font for £1.47 and I've been charged twice then a 15p charge as well.. I know it's not a lot, but it is to me. Just wondered if anyone knows how I get a refund.
