Groceries Not Delivered

I placed a grocery order on Tuesday morning at 8:30 for a 10:00/11:00 delivery. They never delivered, my emails were ignored, my cries for help were eventually ignored too on Twitter.

I had to call now (Thursday afternoon) and they are telling me they have refunded me it will take 5 to 7 working days - what are we supposed to be eating in the meantime?

On their app they say the order was delivered.
