Respected Sir/Madam,
My self Samiran Biswas today I faced a horrible bad behavior from your post office delivery agent (Mrinmoy Paul). Today he called me for my ICICI bank Cheque book delivery, I told him to deliver it to my mentioned address to my parents.At the time of delivery he did not call anyone from the outside of my house. When my parents told him that why he directy visited inside of my house he used slang language towards my parents. I can't understand what's going on in India post?
I called many times at Desh Bandhu Nagar post office but no one picked up my call.
