BUY - Social Commerce Marketplace app.

Hello, I want to inquire about the purchase of the Social Commerce Marketplace - Android Source Code app.
I read a lot of bad reviews about the company that created this app: Hitcomsolutins. Their website doesn't work very well anymore. I am afraid to order their application via codester.com. That's why my question is. When I buy this app, does codester.com send it to me, or does Hitcomsolutins send it, which doesn't work very well anymore? What if I order it and they don't send it to me? Is there a money back guarantee?

Thank you for your response.
