You took your family to a nearby restaurant. You were disappointed with the meal and wish to complain to the manager. v.7

Dear Sir or Madam, My wife and I visited your restaurant to celebrate our third wedding anniversary on March 20th, 2019. Unfortunately, we had a very negative experience due to a below-average meal and poor staff behaviour. I want you to investigate the reason for such a terrible meal. Otherwise, you are going to lose customers. We arrived at your restaurant at around 6: 00 pm and ordered Doro Wat for our main course. But it tasted astringent due to overcooking. Even after we told this to the waiter on duty, he did not pay attention and told us to complain to the manager instead. Besides, the fruit punch that my wife ordered had no orange juice in it, though the menu stated so. This was very annoying which actually ruined our dining experience. I demand a full refund that I paid for a worthless meal. I also want you to take actions against the waiter who denied to pay attention to our complaints. I look forward to seeing you take immediate action regarding this matter. Yours faithfully, K. Henok
