Please sort out your **** store!!!!!!

No happy with the service I received on my query logged regarding Debonairs Pizza Avonwood

I ordered pizza from your store on the 26th of March 2020, made payment via the app. Guess what till today no pizza was delivered. I phoned but no answer. I emailed, I phoned to get answers but still no one could give me an answer, yet ever call centre agent I spoke to said the manager communicated on my query to say he tried to get hold of me. I received an email from Famous Brands with a CAS number and then the communication started. On the 9th of April 2020 I received a SMS to say my case has been resolved......till today I don't know how as I still did not receive the Pizza I ordered or received a refund. I made numerous calls and was then given a new CAS number and again been told that a request is made for the manager to phone me. Surprise, surprise here I am 53 days (1266 hours) after I placed my order and still no news. This service of this store is ****.
