My overbite is very large. Do you think SmileDirectClub would work for me? (photo)

I have always wanted braces but braces are way too expensive for my parents. I’ve recently found out that smile direct club offers a cheap plan where i can afford myself. Can smile direct club fix my problem? I have a large super bite where i can fit a finger in between on my top layer and crowded issues on my bottom layer. I believe my double chin was form due to this problem too, can i remove the double chin if i use smile direct club? Or should i use braces?
