McDonald’s complaint: Threatening Staff

Visited the drive thru on 13621 at 1515. I ordered a chicken legend with bbq sauce 6 nuggets and a vanilla shake.
I asked to double check the order as laminated sign was obscuring the order screen. The lady taking the order was very difficult to hear and was confused as I had asked about the laminated sign said some of the chicken range was in limited supply. When I collected my order I asked where the burger was and was told in the bag. No it’s not. I said it’s nuggets and was told I didn’t order the Legend. I said I had ordered it with BBQ sauce, which was in the bag plus a further sauce so 2 x BBQ sauce one 6 nuggets and fries. So she clearly heard my order otherwise why was there 2 sauces.
I said I wasn’t happy as I have not been given what I ordered. I was told I had to go back around and queue again – this made no sense !!! I had food that would have gone cold.
A manager appeared and I was told I had to go and wire or leave. The Manager “Drew” then told me to stop insulting his staff… for getting upset that what I had ordered wasn’t given to me or offered for me to have it and to wait in a waiting bay.
I was then told he would call the police …. So I was threatened and insulted and denied ordering again.
