I booked a trip to Japan on Aircanda who due to aircraft malfunction they rebooked me on u tied/ANA flight but they had my bags locked in that aircraft and I stayed 3 days in Japan with no bags not even my carry on since it was a small aircraft they took it from me in the door.
I had to spend almost 200$ on basic stuff and cloth so I won’t ruin my trip.
now I am
back and kept my receipts but AirCanada said I should ask ANA for reimbursement since ethers were the ones who lost my bag.

ANA said they never received my bags from Aircanda and now no one is paying me back.

Any idea on the what should be my next move ?

thanks
