Broken seats at N1 city

We had pre-booked our tickets online to watch 'the nun' at N1 city on Saturday 8.9.2018 @ 18h00. When we arrived we were unable to print our tickets due to the fact that the seats we had selected were broken. We were then told that we had to wait until everyone else standing in line had booked their tickets before they could give us other seats. Eventually we got other seats right in the front of the screen and one of the seats were also broken!!! this is completely unacceptable because the whole reason we booked early was to avoid the queue and we did not enjoy the movie at all due to the broken uncomfortable seat. The broken seats should not be available to book online and should be removed from the website or better yet , they should be fixed!
