Absolutely nothing!

I have no idea what I'm doing wrong, I feel like my comprehension of this platform is lacking somehow? Why if you receive an order in great time and condition, better than expected, would you wait to pay the person for it? It is torture. Seller has to wait for shipping, and then wait on people to rate or 4 days to get paid, and then wait for a direct deposit to go through!?! Why would the buyer just let it sit? No contact, no response? Its terrible rude! Please rate your sellers!
