Very poor delivery and customer service

First order went well. All subsequent orders disappeared off the app and the website. 2nd order was not complete. 3rd and 4th orders did not arrive and I take it they have been cancelled and I have been refunded. I did get an email that they were trying to deliver today. I got no notification of the cancellation and refund. Their communication leaves much to be desired. Mailboxes are full so you cannot leave a message. They do not respond to emails.
