Recurring charges without purchase history on iPhone

Last month I was charged £12.49 and the same yesterday. I’ve looked on all subscriptions on my phone, bank etc and my purchase history and can’t find it anywhere and I’m not connected to any Apple family whatever and I was also charged £1.99 like 5 times in one day when I didn’t make any purchases from Apple Pay. It might not seem like a lot but it’s very annoying. I’ve tried to get a refund or dispute it but with it not being on my purchase history it’s very difficult. I’m stuck and don’t know what else I could do
