Добрый день.

Помогите пожалуйста разобраться со следующей ситуацией. Заплатил деньги за 2 единицы товара,

продавец прислал 1. Проблема в том что Case открыт по несоответствию описанию, а не по недополучению товара. Проблему описал в "дополнительной информации" к case Продавец перестал отвечать на сообщения, кнопки escalate нету. Каие мои действия ?открывать новый case а этот закрывать и почему нету кнопки escalate 3 дня прошло с момента ответа продавца. Спасибо.
