Logo development

About 6 months ago, I created a logo with a logo generator on Wix. I love the logo, and want to purchase it now. I have the logo, but can’t find the site to purchase it.
I do see another logo generator that is free. But I can not duplicate the logo I created 6 months ago.
How can I purchase the logo I created? Where is the logo generator that existed about 6 months ago?
