Lieber Florian Gestern Abend 12. November um 18:30 Uhr zeigte unsere Heizung eine Störung an. Telefon an dich und 5 Minuten später warst du bei uns zu Hause. Um 19:00 Uhr Defekt behoben und die Heizung läuft wieder wie geschmiert. Herzlichen Dank für diesen geschätzten und tollen Service. Heinz Lehmann
