I'm being charged 3,2%+$0,3 on payment, although it's supposed to be 2,9%+$0,3 (see screenshots)

Hi Community! Compare these 2 screenshots, Shopify is charging me 3,2% (via Shop Pay) instead of 2,9% what they are offering on their plan pricing overview page (assuming Shop Pay fits into that category, which it should). Why is that? Is there a way to directly contact support by chat or email regaring issues like this one?
