WDH-FRA with my wife. Big mess to reconfirm the flights in WDH (computer breakdown) incompetent employees not willing to help. Checkin OK and quick very lousy lounge at WDH no priority boarding chaotic "rush" to the aircraft. Aircraft standing there the whole day and no traffic but able to depart 30 mins late. Worst cabin service ever experienced no meal choice available slow and incompetent staff. My wife went to the galley to ask gently for something to drink together with the meal the chief FA came to our seats and scold us "you have to be patient we have other things to do". Were treated like disobedient pupils no need to say after meal there was no more service and entertainment system at my seat was defective. Rude wake-up in the middle of the night 2.5 hours before landing for what they call a breakfast. Incredible and a great pity for the wonderful and friendly country of Namibia next time we fly again SAA despite of having to fly via JNB. We traveled last time in 2006 with Air Namibia and things have turned from good average to lousy.
