The best restaurants serving Fast food food in Old Harlow Harlow East of England

Very disappointing food and Multiple items missing, I have made 3 phone calls and sent 3 e mails and have been completely ignored by management. I am a frequent customer who has never had cause for complaint previously yet no one has bothered to address the fact our £50 meal was of a very poor quality on 25/11, the meal was disappointing enough and being ignored makes it ten times worse - very bad manners
