First Flight Couriers — Really Bad behavior of staff

Address:

Hyderabad, Andhra Pradesh, 500032

My friend couriered me some documents from Bangalore to Hyderabad. Due to some official reason I was not in the office at that particular point of time when the delivery boy came. So I told him to transfer to madhapur area because its easy for me to collect it from there.
From two days i am following up with him but we are not getting any response and today when I called him he told in a VERY HARSH WAY that the parcel is returned to Bangalore and he also told me that he got confused ( i dont know how and why)

Person's name: Shiva
Number : [protected]

Consignment no: F991B2255853

First of all I want full information on this ASAP and An apology from Shiva.

I want an immediate action on this task.
If I did not get any reply on this then I'll escalate it to the higher level without any hesitation..

I have send this mail to [protected]@firstflight.net 4 times but I am not getting any reply and I am worried about my courier now.

Thanks
