This is a matter between you and gandi. We really have no control over what they do or do not do. They originally entered a contract with a legal entity that no longer exists. (Mozilla Messaging) So I really do not know what happens from a legal perspective. But from where your sitting, if you want action I suggest you ask Gandi. https://www.gandi.net/support/contact/ From a personal perspective, I can understand an automated form accepting a request for an email address of a domain you do not own. The folk that designed the form probably never considered that someone would try and register an email address on a domain they did not have a legal right to access. My guess is no human has been involved in the process up until now and you will get a refund once you get in contact with a human. But that is entirely my personal views. I work for none of the parties to your dispute so have no standing in the matter at all..
