Ibibo Group / Goibibo — flight ticket cancellation by the executive without confirming with me

This issue started on 15th august after one of the goibibo executive cancelled my ticket without my confirmation.
I had put up a request of "know your cancellation charges" on 14th aug 2019 evening.
I wanted to know my refund if i cancel.
On 14th aug i generated the request and on 15th morning i got a call from their executive.
I was explaining my concern on the call and i said "i want to cancel but i want to know my refund" and while saying this the call got disconnected.in a matter of 5-10 seconds i got a message that my ticket from chennai to ahmedabad on 31st aug 2019 has been cancelled & meanwhile i was trying to call goibibo which became impossible as we only reach a bot and i had to put up messages on their fb profile. How can the so called customer care say that i had put up a request for cancellation when i know i have chosen the mentioned option above. Who gave them the right to cancel the ticket without confirming with me. This is a case o[censored]tter negligence by their executive and i feel harassed to talk to the people of goibibo as they lie, mis-quote me and give stupid suggestions. One person offered me a 300 goibibo cash that is totally useless, in the name of my hard cash they are offering me a virtual amount which is really absurd. Instead of accepting the mistake and sufficing my loss am getting stupid suggestions. I am totally disappointed as we earn money with hard work and these people are ready to eat it. I thought of rescheduling my tickets if the refund would have been too less, i had to rethink about the travel due to some family emergency. I got rs. 236/- as a refund. Pnr r1ytyr
My return ticket is still there which is obviously useless.
I need a refund for the ticket they cancelled.
I have attached the image of the cancelled acknowledgement on my email id.
