I placed an online order and waited one hour and 20minutes for food to be delivered. Then I CALLED THE STORE to enquire about my order and the manager told me that he will follow up and see what he can do and call me back. The I received an sms to say that the order has been canceled but I paid for it already, the manager told me he will refund my money and till now it hasn't been done, very unhappy about this service.
