Disappointed! A Famous Brand like Debonairs can do better

I placed and paid for pizza delivery (from Engen Hatfield Debonairs) via the Debonairs online platform at 14:52. The order was accepted (order ref: # 577925) and funds were drawn from my bank account. At 16:01 I called the store and spoke to Eve who could not confirm if my order had been placed. She further stated that they only had 2 delivery drivers which didn't explain why the order had not been processed. She said she would look into the matter and contact me. She did not. At 16:36 I called Debonairs Customer Care and spoke Fundi who told me she would follow up with the Engen Hatfield Debonairs and give me feedback. She further said she would register my complaint and that a complaint number would be sent to me via sms. This did not happen. At 17:04 I called the customer care centre again and spoke to Roshay. It took over 7min (at my cost) to identify my previous complaint on their system and to establish the fact that the follow-up promised by the previous agent was not carried out as "she could not reach the store". No reason was given as to why I had to call customer care again to ask for the complaint number and feedback as that was the reason that my number was taken. In fact, upon requesting to speak to a supervisor, I was told that there was none. It is now 18:05. No pizza; no progress.
