Had my booking done Nov-2019, Tried to cancel my booking (Air Canada) starting from 2-weeks before our flight due to COVID-19. Tried 72 hrs before our flight (3 x a day), emailed them a couple of times, still not able to contact them in any given time of the day. They sent (via email) me a new flight schedule through Air Canada asking to confirm or cancel through online and replied back via computerized automatic reply saying one of their agent will contact me back BUT NOBODY from CheapOair called/contacted me. I can't even cancel it online because my original reference booking number NO longer valid and accepted.
Come less than 24 hrs before my original flight schedule, finally I decided to contact AIr Canada direct and waited for 30-45 minutes and finally they manage to refund (credit) and cancel my flight.
After all these, till date STILL HAVEN'T HEARD A WORD from CheapOAir.
