Overcharged

Hi,

I've been overcharged this month. My subscribtion plan is the Student option, and it's set to end in 2028, yet I have been charged 237,50 DKK (around 32 euro). I usually get charged 151,50 DKK (around 20,50 euro).

Is there a reason behind this, or was this by accident? Last month I was charged 151,50 DKK, yet it changed this month
