Cancel Premium Plan for Temporary Website

Hi All, I am building a website for my son’s 9th birthday party at the end of the month. I’d like to remove the Wix ad banner and link to my domain, but would prefer not to have to pay for a full-year’s Premium Plan subscription for a site that will only exist for 4 weeks. The ‘sign-up’ information on the Wix site is ambiguous as to whether I can cancel part way through an annual plan. Can anyone clarify or suggest an alternative way?

Many thanks. The wording of the support article is still a little vague with regards to whether a refund is payable if a user cancels a Premium Plan during the subscription period. I suspect not.

The article says about Trial period of premium

If you cancel during the first 14 days, your trial period ends immediately and you are fully refunded
