Cleartrip — Flight Cancellation not informed

My ticket from Bangalore to Hanoi was booked via ClearTrip on 7th Oct 2022 - Trip ID - [protected]VietJet). On the same day my return tickets from Hanoi to Bangalore were also booked - Trip ID:[protected]+1 impacted friend Trip ID :[protected].
On 11th October, we received two separate emails from cleartrip team, that stated that Trip ID:[protected]+1 impacted friend Trip ID :[protected], is cancelled by the airlines. Unfortunately, we noticed this email only by 8th of Nov as these emails landed in our spam inbox. On 8th Nov 2022, we initiated our support call with clear trip seeking for alternative flight options. We spend more than 8-10 hours over multiple calls, with different executives seeking for one of the below option:Alternative flight arrangementRefund plus compensation/support on the variance amount of new reservation.Cancellation of my ongoing flight to Hanoi (Trip ID[protected] and complete refund of Trip ID[protected], [protected] and [protected]The cleartrip everyday seeks for additional 24 hours, which added to a total of over 14 days. Understanding how we were losing time and being pushed around by the support team, we made an alternative return flight arrangement from Hanoi to Bangalore (Ha Noi Ho Chi Minh Kolkata Bangalore), which was the cheapest available option. Prior to making this cancellation, we can clearly requested the clear trip team multiple times, with multiple folks to confirm on the cancellation option for my ongoing flight to Hanoi (Trip ID[protected]
There was no clear response from the team over email or call. Today, 4th Dec, 2 day before my international trip to Hanoi (Trip ID[protected], when I called the cleartrip team to confirm my flight status, they mentioned that this flight has been cancelled. However, I did not get any communication from the Cleartrip team in advance. When asked for the reasoning, they mentioned that Vietjet Airlines has discontinued operations in Bangalore airport till 31st of December 2022. This communication was shared by Vietjet Airlines with Cleartrip over a month back (this date was not disclosed to us). As I understood over the call, this appears to be the same reason for the other two returning flight cancellation as well. However, they had missed communicating the cancellation of Trip ID[protected].
Despite talking to at least 15+ (I trust) different executives over many weeks and explaining all details and requests for cancellation prior, the cleartrip teams executives and escalation leads were extremely careless and inconsiderate in even checking carefully and informing us on the cancellation information on my ongoing flight.
Finally, I am now forced to make new reservations at the last minute, at a cost close to 2.5 times of the original ticket fare to travel to Hanoi and further I have already also spent large amount to make my return trip arrangements. We had even clearly communicated with the Cleartrip team earlier that if the cancellation is available for my ongoing flight, we want to cancel the entire travel plans to avoid any chaos and additional unreasonable expense. There was absolutely no support to even help me make alternative ongoing flight arrangements despite it being their mistake.
