Cleartrip — ticket change from selection during payment

I, Anish Banerjee, have been booked my flight ticket from Dammam to Kolkata and return through cleartrip. My transaction ID is[protected]. During booking of ticket, only one option was available for multiple carrier of Srilankan airline & Etihad airlinethe, which have 1.00 hour layover time in Bahrain. I was select that only option.
But after completing payment, the itinerary was completely changed. The layover time in Bahrain is increased from 1.00 hour to 19.30 hours. Flight no., timing & date everything has been changed from Bahrain to Dammam. Now I am unable to reach at Dammam on 9th Feb and I am forced to take a physical challenge for travelling more than 35 hours continuously (from home to home).

I have sent several mail to cleartrip and they told that I have select that 19.30 hours layover option during booking. Which is absolutely surprising, because in cleartrip site only one option is available for multiple carrier of Srilankan airline & Etihad airline. Which shows total 11.10 hour travel from Kolkata to Dammam.

Without any intimation, changing ticket completely unethical and it is nothing but a mental as well as physical torture. It is nothing to force for paying some additional amount for changing the ticket.

Thus, kindly look into the matter very seriously and arrange my ticket as per my selection, i.e. 1.00 hour layover in Bahrain.
