Make My Trip - Passenger refused to sit in flight

I deepak booked a ticket on **th November **** for my cousin sister Novepreet Kaur. Who was going on study visa. (Delhi-Brisbane). Her ticket was booked with Make my trip, Qantas Airways PNR no. KT*RXT. Flight day **th November **** (Qantas Airways **kg luggage).
As per the timings she reached airport, but at the boarding pass check in counter she was refused to issue boarding pass and the officials said that her ticket was cancelled. they also told that they have sent email to registered mail id but on email ID I didn't get any mail regarding cancellation of flight. It was like hell for her that she was refused to sit in flight.
This was a harrasing situation for her and Even She was surrounded by Police officials and airport police said her that She was travelling with fraud ticket. Everyone can understand that what level of mental stress she was bearing at that time. she was crying a lot.
Then she called her brother and somehow he made arrangement for new flight ticket (Singapore airlines)
Even in Singapore airlines, the luggage was **Kg and in Qantas was **Kg. She paid extra for **Kg weight in Singapore airlines. she paid approximately **,***.**.

Even Rs **** was spent on parking of car at IGI airport. (her father and mother came to drop by car)

I, Deepak also talked to Qantas airways , they told in their technical terms, there is code sharing in which ticket will be reissued within some limited span of time, but make my trip didn't issue the a new ticket. Now its been one month going to be completing, Make my trip mail me every after */* days that our higher team is working on it and will refund the amount soon. One of customer care executive even told me some days ago that Qantas airways make them clear that they have given time to make my trip to reissue ticket but make my trip failed to reissue the ticket. Now you can understand what level of harassment I am suffering from. I also ask make my trip executives that who are person dealing with my case? Who is the higher team? But everytime their answer is same that they apology for that and revert in next ** hours. After ** hours they again mail that they will revert in ** hours. This is happening from last one month. ***** (Qantas ticket) -proof available
***** ( Singapore ticket) - proof available
**** Car parking - No proof available
***** lugggae Cost - No proof available
It's almost * lakh , and the harassment of that girl at airport and now they make my trip harrasing me from last one month. Worst worst worst experience with make my trip. I will never use make my trip services again.

Thanks and Regards
Deepak
