I have 20.02 euros in my account, and the plan costs 19. 98 in total. When I first click the buy plan option, I see an option to use credit to pay for it and a card, but after accepting the conditions, the page only shows a pay with card option.

You normally should get the option to buy stuff using cash credit if the amount of cash credit on your account is equal to or greater than the cost of what you're trying to buy.
It seems odd that you're not getting that option here.
You'll probably need to contact 48 support about this.
