Ucook rotten food

Upon ordering from ucook for the first time, one of my meals which was meant to be fresh for 3 days was not! One of the components being the sweet potato was rotten which is a huge inconvenience and made my entire meal incomplete. When I contacted ucook to complain the response received was that i would received 10% off my NEXT ordered items.. I do not wish to order more items from ucook and i want my money back for the incomplete meal! When stating this to ucook via email I was ignored and have not received any feedback. This is unnacceptable and your after service is terriblr!
