CIBC Aventura VISA Card Consumer Reviews

Have been back and forth with agents at the CIBC Rewards center. Been transferred from one agent to another and no one seems to know what to do. I booked a flight with Westjet and at the time the flight was confirmed. After a couple of days I receive an email from CIBC stating that part of my trip with Westjet cannot be confirmed and all the flight times has been changed. I called CIBC and informed them that the new flights and times will not work for me. Talked to 3 agents, but no luck. It's been 4 days now and still no resolution or call-back from CIBC. It's frustrating and CIBC management should look at what's going on at the rewards center as they do not look after their clients.
