KFC DELIVERY INCONVENIENCE

I ordered on KFC App for delivery at 17:58, at 18:19 I received an sms that said " Hi Saney , our driver was unable to get a hold of you to deliver your KFC. Kindly get in touch with our careline on ***. Team KFC" I immediately called this number, I was told my order has been canceled, then I was promised a voucher to reorder, from 18:27 waiting for the voucher, I then decided to call again at 19:10 I was again promised an sms with a voucher number, at 19:35 I called again and asked for my money because seemingly no voucher will be send, I have to make another plan for dinner which is long overdue, the lady who picked up my call kept on saying she can't hear me, I got even angrier, I spent over R40 on airtime for these calls, I would hold a line before response for the average of 4min each time I called, at this minute 20:14 no voucher and no food has been received, all I want from KFC is my ****en money, they can shove their stupid voucher where the sun doesn't shine in their body, I just want my ****en money.
