Really bad service and very bad staff

Honestly they don't deserve even 1 star.

My flight was at 12, I checked in online this morning, I get to the checkins at the airport and they tell me checkin is closed and that I should reschedule. This was at 11h30

I tell them I have checked in but the lady at the till says I am not and that I should go use the self service machine. I told her that their name is not on the machine and asked if she could assist. She rep**** with sorry she is too busy. I told her the plan e is still there and she can just phone the departure gates and ask them to wait as departure time has noted closed yet. She refused.

Non the less I had to reschedule my flight that costs me more than double of my original ticket.

Most of the staff are not wearing name badges and their attitude is absolutely revolting and that was not just towards me, the poor guy next to me whose luggage they lost and told him that it was not their problem.

I want a full refund for the ticket that I had to reschedule
