Dear sir
I am Bharath Curam and I sent a parcel to my son Arjun Curam residing in Milan, Italy via Speed post, India post. It was booked on 8th March 2019 and was supposed to reach in 2 weeks. Till today it has not reached, even though we have complained none responds to what has happened to the box. It has clothes and dry food items such as powders . I have gone many times to the post office but no response. Please help us to find and get the box back.
Regards
Bharath Curam
