Uber eats not willing to listen

I ordered a caramel sundae from Mc Donald’s and was delivered a chocolate sundae. I complained about this to Uber Eats and my refund was R4.50. I then proceeded to explain that a refund of R4.50 was not adequate as I had spent R63.35 on the order and had to end up throwing out the chocolate sundae because I do not eat chocolate syrup. They responded with “we can see that you have already been refunded for this order and we trust the issue has been successfully resolved.” The issue has only been successfully resolved according to them and not me as the customer who wasted over 10 times the amount they decided was enough as a refund. I have not been listened to as a customer. I have voiced my grievances in multiple emails and on the app support with no avail. I have trie to call them multiple times but they conveniently do not have telephonic services available in my area as yet.
