VULXIES review for IEX

Could I give zero stars I would, you have to pay extra for getting the app integrated between shopify and your accounting system, their customer support is way below average and the only reason they have a high ranking, is because only one other company has rated them as good? For months i have tried getting this system to work, it has been a waste of money I have spend more that 1700 USD on that s***?!?!
