McDonald’s complaint: Wrong order and wait time

I have visited Wynyard services McDonalds on numerous occasions, however my last 3 visits have been very disappointing. On two occasions I have received the wrong order, one occasion I received a breakfast roll the other occasion I received an egg and sausage Mcmuffin, my actual order on both occasions was a bacon Mcmuffin with no egg as I am allergic to egg, so I had to through away my full meals as they were contaminated with the egg. I call in on my way to work so unfortunately I have not realised that my order was wrong until I was at my place of work. However this morning has topped it all. Due to there being a long que on the drive through I parked and went inside to order. I was made to stay in the booth that I ordered in until called. Yet there was lots of Uber Eats delivery drivers congressing together. After 20 minutes wait I asked how long to be served I was told your in the que for the Uber Eats deliveries I asked for a refund as was late for work, staff then said Ill go and get it for you, after another 5 minutes I said to staff ‘It really does not matter about food or refund I will have to go’. I was then handed my so called order from a member of staff who did apologise for the wait. Once I eventually managed to get to my car ( this was extremely difficult as the que now for the drive through backed out onto the A689, which in its self presents hazzard for traffic trying to get in and out of the fuel station and passing traffic on the A689. Besides that I opened my food to find I had been given a HASH BROWN I had ordered A bacon Mcmuffin with out egg!!!!! MY very last visit to this outlet
