JRC Components review for CS Amazon Integration & Sync

This app has cost my company hundreds if not thousands of €. While their customer support (Keterson) does his best to help, it is beyond hopeless when he is trying to help you with a program which is completely broken. For the past 6 weeks now orders import to shopify spontaneously. I have contacted support endlessly to no avail, just told they're doing updates, which is highly unacceptable on any live app. Sometimes orders don't import, it means orders on Amazon don't get shipped on time and badly affect our account health. Sometimes orders import days / weeks later, after the order has already been manually imported. Its impossible for staff to know this and so they go ahead and pack a duplicate order. I would advise anybody against using it if there is any other program out there whatsoever which can do similar functions, inevitably you will find this app is far, far more expensive when you have accounted for the mess it leaves your business in.
