Early in July I cancelled a business class fare for a trip to MJT as was told by that agent that it would take about three months for the refund to take place.

Yesterday I gave a ring to the call centre and asked if instead of waiting for the refund to receive a voucher. The agent put me on hold for a while and then came back confirming that it would take 3 to 4 business days to receive the voucher. A few minutes after the call I got an email confirmation stating that my request had been recorded. That leads to earlier today when I received a new (automated) email from A3 advising me that my request cannot be processed any further as the reason for the cancellation of my booking was not related to any changes to the schedule of my flight !
