Printify: Print on Demand

This app is continuing to ruin my business. * 3week + orders backlog. * System duplicating products in orders and charging me (customer support says it's my fault).
* System does not recognize out of stock items. 20+ manufacturers for item, have fun trying one by one hoping they will have it in stock (1 try = 1 day).
* Once system changes manufacturer they will missplace your print without letting you know and send it to customer. Guess what, its your fault too.
* Customer support is worthless and many more... Only way to get help is to leave bad review. Give me dedicated customer support agent so I can fulfill my backlog caused by printify, I will delete this review and move on somewhere else. If not I will update this review everyday so its on top
