BAD SUSHI - STILL WAITING ON REFUND !!!!!

So on 29/08/2020 I placed a sushi order with John Dory's Gateway Mall and Mr D delivered this to me. The platter that I ordered as well as separate sushi ordered was incomplete and had pieces missing. The TUNA WAS BROWN AND SILVER (So immediately this screamed food poisoning), I called John Dory's Gateway which their landline constantly said that the number is currently busy. I called John Dory's Cornubia Mall which I then got through to Nikki who was very helpful as she got the manager of John Dory's Gateway to call me back. After our conversation I said I need my full refund back and they could collect this order from me as it was not a good site at all. I called Mr D Food customer service and spoke to NABEELAH on 01/09/2020 - She said she would send me an email which I could respond with the pictures I had taken of the bad sushi - EMAIL NEVER RECEIVED !! So I ended up emailing myself - NO ONE RESPONDS TO ME, in fact I get an automated Zendesk ticket stating a waiter will get back to me, its been a week later and no one has gotten back to me. Today 07/09/2020 I end up calling Mr D customer service again and get through to MIHLE - takes my order number and Zendesk ticket - call cuts and as I already anticipated MIHLE DOES NOT CALL ME BACK TO ASSIST IN GETTING MY MONEY REFUNDED. Now, I HONESTLY need someone to call me back telling me the refund has been processed with proof of this being done or ill need to get hold of management seeing that so far I've gone around in circles !! SO FRUSTRATING AND DISSAPOINTING !!
