WORST SERVICE STORE AND BRAND

On the 1st of Feb 2018 I ordered a pizza on the online app from Debonairs Queenstown as I have done on numerous occasions. I received an email and sms confirmation that my order and online payment was received. 2 hours later I drove to the store myself, only to be told that my order wasn't received due to the fact that their internet wasn't working. they didn't want to make the pizza or give me my money back even though I showed the supervisor the order nr, confirmation sms and my bank statement. i was told to wait till the next day. after getting different stories and no refund, I contacted Debonairs Customer Care department and got the Regional Operational Manager for the area to contact me. He assured me that everything will be sorted by the owner and that she will contact me personally. she told me another story about a 3rd company that has the money and will pay it. Till today I haven't received a call or feedback. the owner offered to pay the money on the 12th of February but after several calls and sms's I am still sitting with nothing. It has cost me more than 15 phone calls to different people and nobody wants to take responsibility. NO effort. NO care. NO customer service.
