Multiflyer rebooking
 

I have a multiflyer business class ticket bought from Etihad counter, Abu Dhabi to fly to India. Out of the 6 return journeys I have completed 5 journeys without any issues. I have now booked for the last trip AUH-TRV for 04 May 2016 and return from COK-AUH on 09 May 2016. Unfortunately, after confirming the seats, the airline is not reissuing the tickets. The multiflyer policy allows me to change the destinations and the dates unlimited times. My ticket is going to be expired on 20th May (as they say) and I need to utilise this by flying the above dates. My booking reference is SBOVLX and I am the topmost frequent flier tier member of Etihad (Platinum tier)

I have visited their office twice and made at least 20 follow up calls that caused me a lot of trauma within me. If this is not resolved and adequate compensation is not given I had decided to move legally. It is appalling to see the irresponsible behaviour of their counter staff by passing the buck to others and saying lame excuses. They have confirmed me that there is not mistake from my side at all, but the mistake is done by Etihad staff somewhere.

Can anybody help me resolve and settle this issue?
