Boarding pass refusal

On Sun 1 Feb, went to Mango check-in counter for boarding pass for 11h00 Dbn-Cape Town flight.<br> Presented my ID and Corporate issued travel itinerary (a Company paid e-ticket.)<br> I was refused a boarding pass by Malindi Mhlongo. She insisted that I had to present my company Diners Card, which I did not carry.Alternately, I must purchase a ticket in order to travel to Cape Town.She mumbled something about rules/regs/***** in a twang that I could barely understand.I rushed across to the Mango Sales counter to purchase a new ticket. I explained my dilemma to Shantal Osman who checked with her Supervisor,Clement Isaac,who stated that the e-ticket was in order. I managed to board just in time for the flight. This is the first refusal in 35 years of flying on company business.<br> Come on Mango, your staff needs to be trained properly before being kitted out with a uniform and badge.Different application of rules/regs? Why is there inconsistency in the application of Mango rules?<br>
