Missing product!!!

Hi, On the 25th September 2021. I ordered a microwave from hifi corporation. The incorrect microwave was delivered on the 28th September 2021, I rejected it and send it back with the courier guy and immediately contacted their customer support. They logged a call *** with JD complaints. I called the support again on the 29th September to follow up and there was no update on the call, they escalated to a senior at JD complaints On the 4th October 2021.The senior from JD complaints called me.. With no feedback expect that she will check with the warehouse and she will call me back with an update, I kept calling the customer support for an update daily and they kept telling me that they escalated. On the 8th of October 2021 "5days later" the Senior called me again.With the same feedback from Monday.. She will check with the Online department. An hour later, the courier guys came to delivery the same incorrect microwave, and I sent it back again, so called they customer support. Today the 12th October I still don't have the microwave and Noone at hifi corporation knows anything.
