Worst Airline and bad customer service at their airport

The worst airline ever with the worst service. Flight got delayed in Rome to adidas ababa for several hours and when we finally boarded we were stuck again in the plane at night with not even been offered food or drink as we waited. Finally got communication from captain who advised they waiting on papers than later said waiting on the luggage. When we landed at Adidas Ababa we missed our fight to Johannesburg and they did not try make a plan until we had to complain than after was when they booked us on another late fight. When we asked for letters for work and insurance purposes they refused and blamed the delay on Rome and bad weather which is not even true. They did not even try to give us access to their lounge to atlest get food and rest while we wait again for another flight which we hope does not get delayed again.
