CedCommerce Amazon Channel

Have been using this app for almost a year. I can truly say that this is definitely the worst app I have ever used. My orders are not synced to Shopify correctly, so every time I have to check hundreds of orders and tell them to sync it manually. When I contact support, they say sorry and ensure that this will not happen again, but IT HAPPENS AGAIN AND AGAIN. The subscription prices are so high, but OMG the service and app's performance are terrible. I will end my subscription as soon as finding a similar shopify amazon app. They have ruined my business so far. The only thing they say we are sorry, bla bla....
