What happens when you give a comedy author the control of a supermarkets social media account? Well, we don't know, none of them are that silly. However we do know what happens when the author makes an account that looks just like the supermarkets and starts answering their customers queries.

Welcome to Arseda: the worlds worst customer services. These are 100% real conversations which happened on Twitter.
