I waited for over two hours. After i have contacted their 'specialists" (that what they call themselves as they keep you on hold),
They informed that the restaurant misplaced my order (even though they had sent me a text message and an email that my food was being prepared). I rejected the offer to wait another hour for the food to be prepared and canceled the order, asking for a full refund, which they emailed me would be processed within 3-5 business days.
Absolutely unacceptable. I am filing a claim against them.
