I am livid, disgusted and I not happy with how I was treated as a loyal customer of many years. I placed an order at 15:01, got my order just before 17:00– p what in the world is wrong? The pizza was the worst thing I’ve ever tasted. Doughy, underdone and cold. I WANT A REFUND! I haven’t received any call which focused on addressing the issue, someone just called to ask for pictures proving that the pizza was cold and undone, literally!
