Mr Delivery poor customer service

Recently, for the second time I alerted Mr Delivery consultants that whenever I type any allergies or exclusions as a note, and after saving, and paying, the information doesn't save on the receipt which results in the incorrect order or request. First time I complained they said I must not have typed it. Second time I made sure I took screenshots of typing it and saving it and it was on my app before finally checking out yet it doesn't appear on the receipt. 5 different consultants communicate and each cant seem to understand what I am saying. One asked me to reinstall app.... My frustration is the notion that they state I am lying and did not type nor save the information. Allergies and exclusions are there for a reason. If we order and the order is incorrect it results in me repurchasing another item, for my child with allergies, physically where as Mr Delivery is there offer convenience. I am disappointed in their customer service and responses!
