Air Albania Safety Concerns - Wrong Aircraft Used, Forced Seat Change

First of all, the plane was not an Air Albania aircraft—it was a completely different and unacceptable plane, even though the ticket was purchased from Air Albania. To “ensure balance,” everyone was told they could sit in any seat they wanted after the 10th row. Because passengers sat wherever they wished, I was told to move from my assigned seat 5F to the middle or next to someone in the middle. When I refused, they told me I could leave the plane. I have never seen anything so unsafe and absurd in my life. People pay all that money to Air Albania because they trust the airline; otherwise, there are more affordable options.
