First Flight Courier Service parcel not received within 10 days

Hello,
first of all I would like to tell you that your company has the worst service i’ve ever seen. You recruited or given your franchise .
I contacted the person who is handling first flight service in PATNA mr Rajeev Ranjan, but he responded rudely and didn’t supported me. He gave one mobile number of Bhagalpur person who is managing this first flight service there. He is saying that it is not dispatched by Patna office and Patna office man is saying that it is dispatched on 22-feb-19. Now I am keep calling these guys to get clear picture, but still would able to get exact location of my parcel. this is really worst part of first flight service.
I request you to close your outlet or franchise of Patna and Bhagalpur or take some strict action against these persons. they are thinking about the severity and responsibility of their job.

thanks
