CurvyFabulosityBoutique.com review for Printful: Print on Demand

I just had my first order go through Printful and fulfillment was declined. I have no idea why and there is no real customer support. Because the order was placed thru Facebook, I can't cancel that portion of the order and Facebook will not complete payment. it is a real cluster and there is no "help guide" that deals with my specific issue. I sent two emails, and requested support thru Shopify, but there is no way of even knowing if your email was received because they don't even acknowledge receipt! EXTREMELY DISAPPOINTED!!!!
