Ich habe nun schon zum 3. Mal kleinere Aufträge an Carl Franke vergeben. Jedes mal wurde ich sehr freundlich und kompetent durch Herr Scheifele empfangen. Die Aufträge wurden immer sehr schnell und perfekt ausgeführt. Diese Firma ist sehr empfehlenswert. Immer wieder gerne! Herbert Stoffel

Freundliche, kompetente Kundenbetreuung!
