Cleartrip — cleartrip flexifly cancellation not received

Address:

560103

I booked a flight from prayagraj (Ixd) to bangalore (Blr) for 29th oct 2019. I paid additional 199 for flexifly so that reschedule charge upto 3200 will refunded if plan changes. I did reshedule the flight later to 31st august and paid around 6500 for reschedule. Later i received a link from flexifly to submit bank details for reschedule refund. I did submit the details on 16 oct itself successfully. Today i checked my bank statement and mail to check if any refund came but no, nothing.
I clicked the link again from the previous mail for bank details submission, which is showing error on submission now.

I wouldn't have reschedled if i knew that the flexifly service is a fraud.
