UberEats unfair compensation and lack of communication

I bought an orea krusher and 4 zinger wings at KFC in Nina Park ,Pretoria North via Ubereats on the 14th of October 2022. I was shocked when the guy arrived with the Krusher that was very foamy. He informed me that he himself complained to the restaurant what's their reason for giving a client a krusher that's liquid(foamy), they told him that the machine isn't working properly. I had to put it in the freezer and leave it over night,even then I didn't enjoy it because it didn't have the consistency of a krusher. I then complained to Ubereats and they decided to give me R15 credit on my Ubereats account when I paid R49 for the krusher, I basically only got about 38% of my money back. I demanded they give back the whole amount or give me a new krusher. They didn't respond and it's been days now. It is not UberEats' fault but they are the middle man,they were supposed to make sure the customer is satisfied especially knowing that the food was given to the client in the worst condition. They are giving me the bare minimum and not even responding to my emails.
