I renewed the domain name for my Wix site after a year of free use that expired last July, without renewing the premium plan for my old site. I would now like to use it for my new site, but I cannot find any trace of this domain name—no emails, no details—just a transaction on my bank account. How can I recover it? Do you have any solutions, please? Since I have business cards with this domain name, it’s essential to retrieve it. Thank you in advance for your help. Adèle from France
