Natural Farm Shop review for PayWhirl Subscriptions

App seemed to work but can't communicate with Amazon FBA so it's useless for us. Not happy with the customer service - it took them almost two hours to reply to my inquriy and then he explained that they don't support "pickup orders", when I asked why they're changing the message about shipping methods for subscriptions when sending it to amazon. From there, it took him another 20 minutes to my reply where I said I'm not asking about pickup orders... After another 2 hours going back and forth, I gave up and realize this app doesn't work for us.
