Zomato — No care taken while delivering orders

Zomato doesn't listen to complains. Last 3 times, I order food, give instructions to both the restaurant manager and delivery boy and still don't get my order fullfilled. Zomato shows very high prices compared to actual food prices in the restaurant and very frequently nowadays delivers wrong order even giving non-veg to us vegetarians once and still the complaint portal doesn't work and bots are there which are completely useless.
