Extremely poor customer service

The worst service I have ever experienced. We got caught in Gauteng traffic about 2, 5 hours before our flight, and saw that we might not make it in time for baggage check in. Me and my wife tried to contact them, and wasted in excess of an hours airtime doing so. We sent an email to their "urgent" email address too. We ended up buying 2 new one way tickets which cost me more than our initial return tickets did. They take at least 20 minutes to answer a phone call. And when they eventually do, the operater acts as though they can't hear you and hangs up. I still haven't received a reply - other than an automated response- from their "urgent" email address.... It's been 13 days. Their "flexible flight times" option when booking online, is just another money making scheme. I would recommend anyone to avoid doing business with them. They shrug off any responsibility, and are very unwilling to assist when you finally reach them.
