Poor service that amounts to theft

I am writing to formally raise a complaint regarding my recent experience with Lift airline.

I paid an additional fee for an exit row seat as part of my booking. However, upon check-in, I was assigned a different seat—specifically, a standard middle seat. Not only is this a clear downgrade from what I had paid for, but no prior communication or attempt to resolve the matter was made before the flight.

This is unacceptable. Charging passengers for specific seats and then unilaterally moving them to a less desirable option without refund or accommodation undermines trust and service quality. I expect either a full refund of the seat selection fee or a satisfactory explanation and assurance that this will not recur.

I look forward to your prompt response and resolution.
