Terrible service and app. Money taken for a failed order and they do nothing to return the money straight away nor help you with your complaint. There is no facility within the app to raise concerns about failed orders just a telephone number and that service is poor. You try to contact them on twitter and email and you get the same level of poor service. How difficult is it to code if an order fails, you return the money straight away. I am also a premium customer whatever premium means 🤷
