Adding extra payment in /checkout-cart/

Hi, cs cart 4.5.2, on checkout-cart, system adds the cost of the payment way “cash in delivery” without customer choose this. How can i remove it ?

Check and make sure it’s not set up in your payment method under “Surcharge”. Administration->Payment methods->YOUR_PAYMENT_METHOD

I check it, it has the cost of this service. You mean to delete that cost? If yes, then there wiill not be a fee of €2,50 for the “cash on deliver” service.

First available payment method is selected automatically. I am afraid, there is no way to change it without code changes
