On 15th July I ordered One veg over loaded pizza and one potato cheese in Dominos via the Zomato app. The delivery executive has told me that the item potato cheese is unavailable and will be refunded. I called up to Zomato customer care and they said me to check with Dominos. I raised a complaint with dominos and I dint get proper response. They said it will be refunded but the amount haven't credited to my account till now since that day.

Note: The bill format is JPG, still I am not allowing me to upload here.
