Entreaguas Wearable Art review for Appointment Booking App Propel

I would not recommend this app, mainly for the customer support. I ask the app's customer service if there was a way I could test the premium plan on a development store without having to approve the charge. They told me it was not possible but that I could pay for it, and if I did not like it I could ask them for a refund since they had a 30 day money-back guarantee. I pay for the plan, tested the app for less than 1 hour, decided that it was not what I was looking for, and proceeded to ask for the refund. Now the app's customer service is telling me that I should talk to Shopify directly, and I have been trying to get the money back for a couple of days. In this sense, I felt misled by the app's customer support, they made it look like it was easy to get a refund if I didn't end up using the app for my production store, but it has not been true so far.
