Average Food Delivery Service. Review on Zomato

I am using Zomato app since 3 months and I have ordered food from here many times. I have faced some issue in the beginning due to some location problem. Delivery agent's google map was not working properly and he couldn't deliver food on time. I have faced the same issue two times from Zomato. Delivery boy was too friendly and humble person first time but the second time delivery boy was very rude, shouting and teasing me like anything so I contacted customer care and informed about the issue with delivery boy and they promised me that you won't get this issues in future. I haven't face that kind of issue till now after that. Most of the time I received good service from Zomato. So I can't say that its too bad or too good So I can say that its average food service. We may get some issues with them sometimes. According to me good things happend mostly as comparing issues. So I like Zomato.
