Dissatisfaction with airlink service

I had to fly to Mozambique business on flight number 4Z207 from Johannesburg to Maputo i went through customs and got on the transit bus to the plain when we disembarked at the aeroplane everyone got out my self included I walked away from everyone about 15 meters from everyone and lit a cigarette the ground staff motioned to me to put it out witch i did immediately as I got to the door of the plane then the airhostes stopped me from entering the plain and said that the captain had denied me access to the plain as he saw me lighting a cigarette next to the bus but as I said I put it out immediately but he still denied me access to the plain n then he proceeded to call the police even the ground staff couldn't believe what he did then the ground staff took me to arrivals to stamp my passport back in.the ground staff helped me to go back to customer service to try and get a ticket later in the day,but the airline said I can not get a refund because my plain has left with is completely unacceptable and when I wanted to purchase another ticket for later the same day they refused and I had to purchase a ticket for the next day how ever ,I feel that they have ******** took 3000rand plus from me and made me pay for another ticket to Mozambique the next day regards ettienne rothner
