Cleartrip — same name tickets

I booked a ticket for 2 passengers and the ticket was booked by the same name
Now cleartrip people are not ready to change the name and they are asking me to cancel the ticket and book again..
For their mistake why should i pay the cancellation charges..
Before booking they need to check what are they doing.. How can someone book two tickets with the same name..
It’s just a money making strategy nothing else..
Cleartrip people are to help customers not to increase their problems..
I hope they solve this issue and make sure no one else suffers with same problem..
