Jonathan no need for being so rude. I emailed over a week ago actually. Not just 20 minutes. 20th of April and asked the same question. Did not get a response and now I do here with you acting like I am impatient. I think a week to respond is more then enough time. It was only after commenting on here I get a smartass response.
It was a simple few questions whether the app was suitable or not, and obviously not, and with customer service response time like that, glad I did not go ahead with bothering with an app that isn't capable of truly handling exchange and refunds.
