I accidentally bought something using san van bucks

So i just bought the deluxe pack and i was scrolling thru the shop, and i noticed the Halloween pack. I clicked on it and i bought it thinking it was a crate that cost 2k halloween coins or whatever. I bought it and I want to know if there is a way to get a refund or if there ever will be because I really don't want this entire pack and I would really like a refund.
