Consumer Redressal

I have booked by tickets from Del to Mumbai ( AI435) and the travel date is 17th Jun,2020 but there is updates for this flight, If its cancelled by the Airline than request you to please refund my money for the whole ticket form Del to Mumbai ( 17th Jun,2020 and return journey from Pune to Delhi ( 21st June,2020) . I have requested to AI official ( Cx Care ) to please look in to such cases were the customers are not being informed in advance about the flight status and schedule. I have contact Ease My Trip ( Ticket Agent ) and as per him he can offer me rescheduling for my Del to Mum flight because that has cancelled and can't offer any thing on return ticket from Pune to Delhi on 21st Jun,2020, its operational. Its really funny-- If man will not travel to his destination and how he can come back on the return flight ---Stupid reply I got form my agent that unless Airline will not allow me how I can offer you rescheduling on return flight. Please help me in this case ...How to proceed for full refund or get an extended return time at least one year without any penalty. Regards, Sanjeev Kumar
