avalove shop review for Yoycol: Print on Demand

I would love to use this service. I designed about 68 items for my shop that went live, and discovered there is no shipping settings on any of the items. The settings did not migrate to my shop. I have spent almost a full week trying to get a hold of someone from yoycol, with no response or small responses that are not helpful. It's so sad I would really love to use this service, but there isn't any customer service, I can't even get the shipping set up in Shopify and it's been a week trying to contact them. If no one gets in touch today, I'll have to delete this app and remove the 68 products I would love to sell. :(
