Yasong Vorna Valley Horrible service!!!!!

Yasong Vorna Valley is the worst takeaway place. I placed an order through Mr Delivery and only when my ordered arrived, I noticed that I didn't receive my full order. I called the manager at the restaurant, and he tells me that they ran out of the item to supply me with, but no one had the decency to contact me and inform me. The manager then stated that I should place another order, pay for that and then he will be able to send me the items that I didn't get on my first order, which means that I'm paying twice for something that I didn't get the first time around!!! This is utter nonsense. I paid for something that I didn't get and I won't even get refund for that item that I didn't get.. Secondly the manager asked me to come through, if I wanted to drive myself to yasong and order my food, I should have done that, but hence why I ordered through Mr Delivery service because I didn't want to leave my home, so I must waste my fuel to go and rectify a mistake that Yasong Vorna Valley has made. Can someone please rectify this problem? Either refund me my money or deliver the item that I paid for asap! Worst service ever!!!
