Flipkart — About delivery agent

Address:

Hastarganj, Hajipur , vaishali, bihar

The delivery agent had come to deliver a new phone exchange of an old one .At the time of checking the old phone he added the double amount for a single fault and I told him this is wrong then he started misbehaving . He doesn't even know about the rules and regulations regarding the exchange of the phone. so I request you to take action against him, and next time please send someone who has all the knowledge about the field in which he is working.
