Vielen Dank für Ihren Anruf vom letzten Freitag.

Es tut mir leid, dass Sie Probleme mit diesem Antikörper hatten.

Wir haben nunalle Röhrchen die wir an Lager haben überprüft. In keinem unserer Röhrchen hierhatte es ein Präzipitat. Das Problem scheintnur das eine Röhrchen betroffen zu haben, und wir können Ihnen daher ein Ersatzröhrchen senden. Ich werde Ihnen deshalb wie am Telefon besprochen,ein kostenloses Ersatzröhrchen senden.Diese Sendung hat die Referenznummer x und sollteMittwoch bei Ihnen ankommen. Das neue Röhrchen ist natürlich auch von unserer Garantie abgedeckt.

Ich wünsche Ihnen viel Erfolg für Ihr Projekt. Bitte zögern Sie nicht, sich wieder bei uns zu melden, falls Sie weitere Fragen haben.
