Cleartrip — invoice not provided.

I booked tickets through cleartrip trip id[protected] (Date of journey 15 april and 22 april) for cathey pacific filghts. Even after repeated e mails and many follow ups the airline as well as cleartrip have not provided me invoice for full amount. Cleartrip is just giving a receipt and does not understand that it is differrent from invoice. It is giving invoice only for its own service charges. It fails to explain from where will the invoice for rest of the amount come.
In its last mail dt 5 june 2018 cleartrip mentions that the airline has refused to give invoice since gst was not given at the time of booking. I think they can deny gst benefit but still they must give invoice.

Hopeless airline and hopeless clearttip service i would say.

Tatra and make my trip are far better.
