Air Asia — disappointed in the ground crew

Hi, On the 27 sept 1430 we rush to our gate for the flight at 1440. The ground crew doesnt allow us to go in and insist us to leave the area unless we buy a new ticket. The air asia crew ask them to unload our luggage but the upset thing is they have time to unload but no time to let us enter. The air asia crew at first did not offer us solution until we suggest to take other flight. We are very upset in the service and her reply.
