Headcounts at CemAir; a mathematical challenge!

Making a booking was not a problem at all, did it via Discovery app.

The morning of the flight however, after check in and entering the boarding area, the doors of the plane was closed before I could board - to confirm, I was not late.

The hostess made a head count and since the required number of passengers were met, they closed the doors without allowing sufficient time for boarding.

My luggage were already on the plane as well, and I missed my flight as the captain indicated they are not opening the doors again. I was stranded.

Yes, CemAir have offered that I can use the ticket within 12 months, but the problem is lack of communication, no calls or apologies, nor reports on why an incorrect head count was accepted, if I am still in the boarding area.
