She was in Ukraine at that time, and then she bought an iPhone X (then it just came out), she immediately noticed that something was wrong with the phone, and a few days later she was freed up for service. They took her phone for a check, after 2 weeks they said that there really was a problem, and only a month later they returned the phone. She was shocked by such a long wait, after a few weeks she broke it and after that, it broke every month, six months later she bought a new iPhone)
