DTDC Courier & Cargo — unlawful cancellation charges

Address:

Nashik, Maharashtra, 422003

Dear Sir,

I book on document on 26th feb 2018, and cancelled it after 1 hour.
DTDC vendor charges me on behalf of DTDC 40% and did not gave me receipt of 40% Deduction.
He just returned the booking receipt and mentioning cancel and 40%.

I asked for bill. they said this is how they give and i did not found any where mentioned 40% in there terms and condition.
