I placed one orders at around 3:30 one of which got order and deduct payment through paytm and the other was preparimg. After an hour of waiting when I contacted the customer support chat option, in chat box give me delivery boy number and then I called to delivery guy but he is not received call. The app immediately showed that the order was preparing till right now and the delivery not despatched or not on the way but its been around long time 3.30 to till time means 8.45 pm means to 5 hour that I haven't received any delivery, the live chat feature wont work and the delivery guy isn't receiving my calls.
Pathetic service...
