Even though the site can be buggy sometimes, I cannot oversee the complete lack of competence by your side to actually miss the fact that the files haven't gone through. Even the best of the best platforms sometimes have problems in file sharing services and it is usually due to user error. In addition to that, the way you are expressing yourself gives a clear indication that you lack the necessary communication skills to work in a professional environment.
Just by a short glance at the order page, you can see if the seller has received your files or not. You should take the necessary steps and educate yourself on a platform and its services before signing up for last minute projects.
