Translation of bandwidth in German

All travel agents, but one, were all pritty unreliable as one could perceive immediately. We did not care for a dollar more or less and everybody promised the same which was not convincing.
I'm from Switzerland and I speak German as mother-language. I will try to help you to learn German! We speak French, Italian and German in our country. I heard that in the US Spanish is becoming more popular.
Many thanks for your letter. I am delighted to tell you that I have passed my exams and am looking forward to the next year. Meanwhile I am planning a trip to Costa Rica and some places around there.
