Mr. Delivery Unsatisfactory Service Delivery

I had a missing item from my delivery on Friday and e-mailed and called asking to have the missing item delivered. For some reason that is extremely difficult for Mr. D. I advised I ordered the food because I wanted to eat it and asked that they try to get my item delivered and call me back if they had challenges. I received no call and no delivery, just a standard apology on Monday with a credit of the amount of the missing item to their Mr. D app. After advising them that this was unacceptable and only beneficial to Mr. D, they sent another vanilla apology e-mail. Not only was I inconvenienced on Friday but now am further inconvenienced by having to utilise a credit on their app, order additional items, pay delivery fees and a tip or go through the process of trying to convert that credit to a refund on my account. They remain firm on their vanilla apology.
