Does anyone know how I can change my email address?

I've tried changing my email to another multiple times through the settings but it's impossible. I have also tried to contact support but they do not answer. I thought about deleting my account and then creating another one with the email linked correctly, but it's also impossible. It's really frustrating because I want to use listal and set it up properly, but I can't do it and I can't find any way to help

Have you tried messaging Tom directly, he maybe able to assist?
