Horrible experience

Horrible experience i ordered my food at the self service kiosk for table service(a grand chicken meal, CCF and an extra fries) waited 15 minutes and stuff nothing, i was the only person in the store but yet they still taking extremely long. I proceed to go to the counter to ask where my food is and they respond with “it’s almost done” another 8 minutes pass and my food comes with the exclusion of my grand chicken burger, i ask where is my burger and the waitress who brought it says they almost done and she will bring it back another 10 minutes pass and we have finished all the other food and still not received my burger i go to the counter to ask where is my burger, they don’t apologise or anything and merely just says their excuse of “we lost the receipt” but then they bring the burger out, says nothing and just gives it to me so explain to me : It takes 23 minutes to make my order when i’m the only person in the store ? it takes 30 minutes for me to get just my burger ? and the waitress is so bad at memory that from the time she brought my meal excluding the burger and says she will bring it when done and then she forgets all about it and then they lie and say they lost the receipt and didn’t know who’s burger it is when i’m the only person in the store ? what dumbfoundness this is

let’s not even get to the fact that the stall in the men’s bathroom is broken and j almost got locked in because the slider is broken and doesn’t work

I am definitely writing an email to management
