On the 14th March my family and I were due to return back to the Uk but we was refused our flight because we had not filled in PLF. We new nothing of this form and whilst we were filling it they made us miss our flight. We returned the following day for the net flight, then they asked us if we had a negative covid test, again we new nothing of these unlawful procedures as they were introduced in January, again we were refused our flight. From the 19th of March Ethiopian airline stopped travel to the UK, and my Family and I are stuck in Ethiopia incurring cost we can not afford, the Customer service we have had to deal with has been nothing but disgusting, dismissive and unhelpful, in fact, they are in the wrong job, what I did learn from them is that they do not want to incur £2000.00 penalty from the UK, even after telling them its going to be a lot worse when you get sued. I would like a refund so that my family and I can get on an alternative with another airline. Stopping anyone from traveling is unlawful and I am entitled to the service I paid for and I did not get it. So please refund me,
