I purchased plane tickets with rumbo to fly to Vietnam via Tokyo with ANA airlines, ID Booking: *******780, ANA reservation SS8SRJ, the purchase was on July the 5th 2021, then on September 14 2021 I received a mail from Rumbo telling me the flight was cancelled by ANA and that I will receive the refund 5 to 8 weeks later, and now 16 weeks have pass and I haven't receive the refund or any information and they don't answer anymore.
