If payment has status FAILED the system still disable dates

Hello team,

i have a big problem with my project. I want your help please.
Let me describe it:
“user choose the dates he wants to book. He selects credit card as payment and the bank reject the payment. The order status on woocommerce is FAILED but the dates are disabled”
Can you help me to make the dates automatically available when the order status become failed (automatically not from admin). Thank you.
