Poor Service

I flew to Johannesburg on Sunday the 17th of September, around 09:00. When I arrived on the flight, only certain people were given headphones and blankets. About half way through the flight, I pressed the call button for assistance to request head phones and a blanket, and numerous air hostesses acknowledged that I had requested assistance and actively walked past without asking how they could help. I was on the window seat and the passenger on the aisle was asleep, meaning that I couldn't get up and go and find an air hostess to ask for assistance. I tried for an hour and a half to get the attention of a person and absolutely nothing happened. This is unacceptable. The passenger should absolutely be the number one priority and should firstly, receive the extras needed for inflight entertainment upon arrival, and secondly, not have to wait or continue requesting help for more than an hour. Also, when I was finally able to get up to go to the bathroom, the bathroom was in shocking condition. The sink was completely clogged, there was toilet paper scattered around the floor and the toilet seat was covered in urine. This is one of my preferred airlines to travel with but after this experience I am extremely reluctant to travel with Ethiopian airlines again, and would not recommend your airline to other people.
