The worst customer experience ever!

I found it interesting that you order three cokes and Mr. D only delivers two cokes. Then when trying to resolve the query, Mr. D tells you that they have a new "standard operating procedure" and they can not deliver the missing coke. To be very clear, Mr. D fails to deliver the order correctly and then tells you they will not correct their mistake! Well, that's just great customer service, a total violation of customer trust and below any acceptable customer service standards. Just deliver the coke and get on with it: your customer has already paid for it, at a premium price.
