Order lost

I have placed an order with Homechoice on the 28/05/2021 online and I tracked my online order and noticed that it says my order has been delivered on the 13/06/2021, I called Homechoice to advise that I have not received my order, I have not received an sms or a call regarding my order, I have been calling since the 14th of June and no one has called me back, I called today and spoke to a lady who told me that this is going to be investigated, I mean why didn’t this investigation start last week already when I told about the missing order, each time I call I got a different story, like your service is just disappointing, can someone please call me with answers, my number is ***
