Go First Airline — Multiple cancellation

Date of Incident - 30th Jun
Full Description
My mother is a heart patient and was visiting Bangalore for her heart surgery. We had booked our tickets back home to Kolkata on 12th Jun for 2nd July, 2022. On the 25th Jun I am given a call and told that all direct flights are cancelled & we need to take a 1 stop over flight which would 8hrs long. Understanding the trouble of airlines I agreed to reschedule it for 29th Jun and take the 7hrs flight. Accordingly, we extended our stay in hospital. On 27th Jun, 2022 again I got a call from airlines & they asked us to reschedule our flight to the next possible date and I agreed to do it for 30th Jun. Now on 30th Jun morning 8am when my flight is at 5.45PM, I receive a mail that this flight is also cancelled. This is extremely unethical. Also, TODAY morning I am not sure where am I suppose to go with this cancelled flight. We called the airlines & its the most unsupportive customer care ever I have spoken to. The only solution they have is to take refund or take a 17hr flight, The first lady Rhea we spoke to was rude enough to cancel the call immediately we asked her to put us through the superviser. We again tried connecting to Gofirst customer care and we reached to a person called Puroshutom (who refused in giving his full name for documentation purpose). We asked him to put us through the super visor and he assured us that we will get a call back.
