In Feb 2019 I purchased two tickets to Vancouver from Hartford, CT for a Sept 2019 departure.
I paid a $297.56 (US) fee for Comfort Economy seats. I received a seat conformation email showing Comfort Economy seats.
When we boarded the plane, we were placed in Standard Economy seats by Air Canada.
I have written several emails to Customer Service requesting a refund for the Comfort Economy fee since we did not receive the confirmed seats.
No satisfactory explanation has been given for not issuing to me the fee refund for a service I did not receive. The matter is clear and straightforward.
I paid an extra fee for a service that I did not receive.
Please issue me a refund of $297.56 (US) as early as possible.

You know it would be wonderful if your airline had a cleaning crew who boarded each
flight before it took off and really cleaned the seats and up right tables. I have
frequently seen wrappers crushed cookies and sticky gum on the seats which frankly
is disgusting.... you want to be number one or what? Frequent flyer
