Uber Eats complaint: In-App order to McDonald’s via ubereats

I placed an order for £43.82 the delivery came and to my dissatisfaction the entire order was destroyed in transit due to the driver being careless and spilling the drinks which entail made the bags spliff and it cover not only all of the food but the driver himself when passing me the delivery. I raised an issue via the app help section and was asked to provide photo evidence which I did ly. I was then told by the agent that a full refund would be processed back into my bank account and should be back with me within 3 to 5 business days. I waited 7 days for the refund not to show so I again used to the help section to query this, I was told that I was not applicable for a refund and for my dissatisfaction I would have a 1 time free delivery applied to my account but no refund for my order. I was extremely irate at this point as I have not only followed all of the things asked of me but I have given them more time than I was asked to wait. At this point I have all screen shots of all conversations had with them and have all photo evidence with the receptive clearly visible on these for them to still dismiss this. My partner has the original photos on his phone but can get them sent across to myself ASAP and will provide them in future if necessary but I do have the screen shots of the original conversation.
