Cleartrip — Wrong ticket

Address:

Jamshedpur

While booking my international flight (Delhi to Da Nang), the booking details showed the check-in baggage of 20 kg however when I received the ticket in my inbox, it showed 0 check-in baggage allowance. The airline booking website refuses to accept the anomaly in the ticket sent by email.
The ticket with only 7 kg cabin bag allowance was Rs 7800 whereas the one with 20 kg was around 12k (that I booked) on the airline site as well as on Cleartrip. I also shared the screenshot of the same ticket that was booked by my friend but Cleartrip refuses to accept it.

I want the revised ticket to be sent with 20 kg baggage included on the ticket.
