2 Missing items and quality issues

On 17 May I ordered a McDouble Small meal and a Big Mac Regular meal from McDonalds through UberEats. The McDouble meal arrived without chips and cooldrink and the Big Mac looked 100% different than on their photos, I struggle to believe that it's really a Big Mac!

I logged my concerns the same night but I was only able to upload one photo. A day or 2 later I logged another concerns with a picture of the McDouble meal too, with a photo.

I heard nothing from UberEats. I then went to McDonalds to complain about the order but they said I must contact UberEats. I immediately went onto their app and saw that one must allow 10 working days for a refund, which I did, and still nothing. There is also no telephone number where I can contact them.
