Zomato — received less portion and spoiled food

Address:

380015

On 3rd sept 2019 i had ordered pizza from 85degree c in ahmedabad, gujarat.
When i got the pizza it was totally spoiled and even i don't get the complete quantity of pizza.
I was trying to contact zomato since 3rd sept 2019 but till now there is no response from zomato side. So what should i do now.
I request zomato to plzz credit me the valid amount of money in my account as soon as possible.
Because i don't think it was worth eating that, i had to completely throw the pizza in the dustbin from it was totally spoiled
