letter of complaint about food service and staff behaviours

My name is Ngoc Ha, a member of Sun group, who regulary meet at a particular your restaurant. I had frequently parties here and was exactly satisfied with everything. Nevertheless, the party recently had a few issues that made me unsatisfied. Aslo, I am writing to due to the quality of the food and the behavior of the staff from there. Nevertheless, the party recently made me very disapointed. I found the food quality and your staff’s behaviours not up to usual standard. On Friday, 21st September we booked a corporate meal for 40 people at your restaurant at 7: 00 PM. However, we were not surely satisfied with the food and service here. Plenty of customers have complained that the steak was a bit smelly. When they called the staff to check again, they received a superfical attitude and did not solve the problem. That made customers actual uncomfortable affecting our reputation a lot. I think you have a meeting with the staff and check the food source. In addition, we require your restaurant to compensate the loss of our group’ customers. About $80 each and apology letter for the mistakes that happened. I hope that you will have reasonable solutions so that we will have better experience when my company return here.
