very angry customer

on the 31 of August I placed an order with uber eats I order from KFC in Bedford centre. because my order was taking too long uber eats decided to cancel my order, the next day I got an email from them stating that since my order did not arrive I would get my full refund and I'm getting R20 off my next two orders (which by the way I'm not interested in) I have tried on several occasions to get my money refunded back to me to no avail. I went to KFC Bedford centre and there referred me back to uber eats. what is frustrating is that they have no contact number not even on their website I tried the help me option on the app and website that im getting no joy and no response. I cant even find their head office numbers. today is the 10th of September and still nothing from uber eats. it was my first time using this service and it will be my last. I just want to get my money refunded back to me and I just want to forget this whole nightmare of a process. hope someone will read this and I will get my matter resolved
