Ixigo — wrong flight booked and cancellation made without request

This is wrt to trip id[protected], I had booked spicejet flight goi to bom of 17.35 18.04.19. I was redirected to clear trip and Until confirmation of payment it showed 17.35 and in final itinerary d time was changed to 5.25.
On having noticed that, i only tried to see what would be d cancellation charges n next minute I received a mail dat cancellation is made and refund processed.
On enquiring I have been told dat the cancellation was done by me but I am 100% sure I have not proceeded with cancellation. In fact if I had to cancel why would I cancel through ixigo n not on spicejet directly, wen I very well know that I would be at a loss of 3k if I do it through ixigo.
Either provide a proof dat I have done it or else refund d entire amount. Next line of action would be to go to consumer forum. Thank you.
