I booked the ticket to my family through oman air website Chennai to Doha on 7th September. (Chennai to Muscat by Oman Air and Muscat to Doha by Qatar Airways).
We got both flight boarding passes at chennai airport and we reached Muscat by oman airlines, but when we were start boarding to Qatar airways from Muscat to Doha, they boarding staffs said they coundn't find our booking in their system. i called many times finally reached oman air call centre they said booking was cancelled by oman air and same thing said by Qatar Airways call centre.
But the issue is oman air didnt inform us the booking was cancelled by airline, at least while boarding at chennai airport.
At airport my family waited for 10hours with two small kids(they didnt provide launch/food/hotel) also they didnt arrange for immediate connection flight, after so many discussion they arranged late night flight.
Now they are asking for any document proofs for compensation.
As per their first email they said technical issue flight cancelled, but flight was on time.
After s0 many emails they asking the document proofs to compensate, whether my family stayed at hotel/anything.
