CedCommerce Amazon Channel

I downloaded this app as i believed it would help with starting to list our products on amazon
when i installed the app it kept telling me to choose a payment plan (none of which had a 7 day trial which is the norm on shopify)
i chose the cheapest one i could so that i could test the app out
Quickly realising the app wouldnt work for me, i contacted customer service with some questions and asked for a refund as the app wasnt suitable for our products
Customer service, instead of advising me on how to use the app, told me to uninstall it and they dont do refunds but would give me a credit to use if i wanted to use the app in the future
Baring in mind that i had the app installed for less than a couple of hours before reaching out to the customer service, and less than 24 hours before uninstalling it
Waste of time and money
