Help with FaceBook user name issue

I created a business page on FaceBook for my company "Making Lending Easy", I am able to choose making lending easy for my name but when I try to make it the @username as well it says the name is already taken. I've tried to search facebook for the owner of that user name and cannot find a page affiliated with it. I'm pretty sure I made that user name in the past but cannot track it down. For now I had to use the name @makinglendingeasyteam I need someone who is extremely knowledgable with Facebook to help me navigate through this and basically act as the tech support for this issue since facebooks tech support is non responsive. I need someone to help me figure out this issue. I've submitted screen shots to help you better understand. please review
