Blue Dart Express — courier not being given

Address:

East Singhbhum, Jharkhand, 831011

I have received a call from blue dart from kaushalendra kumar, jamshedpur office from [protected] informing me to collect a courier from their office as my house was closed as i go to office. When i requested him to deliver it to my office address he simply refused and told me to come and collect it. Why can the same courier be delivered to me at bluedart office by providing the same docs which i would have given him at my office address. It's is simply a policy document and not a bank deliverable. Please look into this malpractice as there have other instances where bluedart convinces customers to come to office and collect docs instead of handing over it to customer.
