Fuming mad with McDonalds Kelana Jaya

I had my lunch around 3-4 PM. I was very hungry when I entered McD Kelana Jaya around 11.10 pm. This what happen:-

• As I entered I notice the environment was rather hot. No air con?
  
• Order my CFO and cheeseburger. I was told to wait for my cheeseburger.
  
• So I paid and waited beside the counter.
  
• Suddenly my cashier was changed with another person. My cashier went missing.
  
• I don't know what time was it.. but i think it was around 11.15 PM.
  
• I waited, waited and waited to be served. My cashier was still missing. 11.18 PM.
  
• It was 11.25 PM. I was boiling inside. An hungry man is an angry man.
  
• 11.26 PM, the new cashier notice I was waiting and ask what I was waiting for, I said cheeseburger. Then cashier shouted to the kitchen "cheeseburger!" and I didn't see any. Tak kan baru nak suruh buat?
  
• I blew my top "HOW LONG I HAVE BEEN WAITING!!?", then she shouted back to the kitchen "cheeseburger!".
• "IS THIS WANT YOU CALL FAST FOOD!!" - I shouted to them. Everyone stopped to look. Then my original cashier came running out, and miraculously my cheeseburger arrived!
  
• While waiting, those Mat Rempit of McD Delivery was staring at me. So the customer is wrong?
  
• Mistakes here?
  
• I should have kept my cool, but I just couldn't contain it anymore. I was hungry and left there unattended. I got really pissed when they had to reorder my food.
• My cashier went missing after taking my order.
• The new cashiers didn't know my situation.
  
• Why the original cashier didn't come back to attend to me or inform the new cashier that I was waiting?
  
• Why was not I informed the time of the burger would be ready.
• Why was I not given a drink and ask to sit down?
  
• The best part I couldn't find any email or phone number in McDonald Malaysia website to file in a complain. So much for customer service and McD is an international brand.
  
• I am going to lay off McD for a while.
