Schriftliche Abschlussprüfung Englisch

Give a summary of the text below in complete German sentences.

ChildLine is a free telephone helpline for children and young people, which received over 10,000 calls last year. You can ring any time of day, any day of the year. It's free and it's confidential - that means that no-one else will know about the conversation unless you decide to tell them. The call will not show up on the family phone bill, although it may if you use a mobile phone. Sometimes it's hard to get through, because the lines are all busy. But keep trying, you will get through eventually.
