Shippo ‑ Simplified Shipping

If I could give a No Star rating I would. This company is not to be trusted. We installed the app to see if it was of any use to our Shopify store. It wasn't so we un-installed it within an hour. We have had 2 payment requests from them since. We contacted Shippo after the first and was told that it was fixed. We have now received another bill for a service that we have never used and never will. Shopify state that after an app is un-installed the developer should delete all of our data, etc. NOT send the end user a bill.
