McDonald's

I placed a McDelivery order on 1/3/26 and part of my order was missing after attempting to contact restaurant with no success I attempted to do an online complaint and have received nothing but the run around. I was 1st told to call location I did not resolution. I was then told to call Doordash which stated that they just delivery I needed to contact location because order was placed with Mcdonalds not Doordash. After that I was told my complaint would be forwarded and handles by restaurant directly and still nothing.
