Pathetic and Unsymphathetic Service

Being a frequent flyer with Comair, my 1st time I was at the check in counter at 12:00 to take a flight departing at 12:25 on a British Airways flight, due to circumstances out of my control, Gauteng, was at the check in counter at 12:00 and the lovely lady tried to assist me if I could still make the flight as she said that they were still boarding when no one answered spoke to Prudence in a very condescending tone said that the flight has already boarded.Advised must go - BA ticket sales & if i am there before 12:25 my ticket is still valid,which I did,waited patiently to be assisted, I get told \oh no"you have to go to Kulula Sales\"""
