Snapdeal.com — Ill mannered delivery man

I have always ordered from snapdeal.
Today 24th may 2016
Got my liptongreen tea order no [protected] delivered around 3. Pm.

As per my information from snapdeal it was "mr. Sumon chowdhury"
Who had come for delivery. Me not being at home, he rang me first for confirmation, his behaviour was very rude. After giving him confirmation, my mom who received the parcel, called me to report his behavior.
He unnecessarily kept on ringing our door bell at this afternoon hour.

My baby who is one and a half year old got up shocked and crying from her sleep.
My father who is unwell also got highly disturbed. Mr. Suman has done it intentionally, and his behavior was extremely rude.
Is this expected from snapdeal???.

Please teach your delivery guys some manners, ethics and humanity.

Ms. Ananta mishra.
