Air Pegasus — Flight cancellation

Address:

560300

I booked 4 tickets with air pegasus for me and my friends. The flight op-124 was scheduled for 3rd jan 2016 from maa to blr. It was cancelled and we were notified on 31st dec and 3rd jan. Since i was unable at that time i contacted customer care in mid january, and was assured the full return will be made in cash or reward points, whichever way the payment was made. On 27th feb, i contacted my bank that why that refund not in my credit card and reward points so they opened requests. After 4 months of follow ups now the bank responds stating that 'airline has declined refund stating that flight was operational and i flew it.' this is harassment from the airline and the bank. Please review the complaint. A quick redressal will be appreciated.
