Horrid service

I visited the M&B on the 15th. I have been apalled and left disgusted at the lack of service. I had to wait up to 50 minutes for my food. When I enquired about the delay Progress advised the kitchen is under pressure. My food eventually arrived * the chicken sarracha less the bacon, extra fries and onion rings. The onion rings were cold so I sent it back to the kitchen. It returned with hot onion rings but cold everything else. Upon eating I found the bun to be dry the chicken overcooked and stringy. I complained once again and neither the waiter or Progress the manager opted to find a solution. I left as I needed to fetch my kids from daycare. I paid for a meal that I did not eat.I would like a solution found. Progress should not be called a manager. She lacks customer service skills. I would like a refund on the meal that I did not eat. I will not be back to the establishment anytime soon and will be informing my friends, family and colleagues about the horrible lack of service
