Zomato — customer care trying to manipulate it

I have not received the order for more than a hour so i have tried to contact customer care. Later on she said that the order is delivered but as in the status it was showing it was still in preparation and the valet is also not assigned so i asked how can it will be delivered without the valet. When i was able to prove it, my order got cancelled. So, i have waited for more than a hour and she was trying to manipulate me but when she found that i can prove it so she cancelled the order. She also lied that i will get a promo code of 200 which she failed to do that. Nice trick zomato!!!
