Useless and Bad Ethiopian Airline

This stupid airline system has cancelled and reassigned my seats upon check in. I’m annoyed and frustrated with their stupidity. My flight from Guangzhou to Ethiopia seat was initially 43C and has been changed to 38H. It has caused me a serve inconvenience at the airport and I called mainland China customer service and there are just as useless as this airline is. My connecting flight faced the same faith as my origin. I hate you for causing me travel stress and anxiety about your stupid system that’s not accurate and up to date. I will post a bad review of your airline everyday of my life until this issues is resolved. This airline stay away bad news bad customer service, it’s all a good excuse and **** to get extra money out of you
