You are an engineering technologist employed by H. L. Winman and Associates, and you are engaged in a lake-level measurement program in northern New York State, working under Government Environmental Studies contract WM-23357. At a critical moment in the program your Hektik Model 370 Water Stage Manometer breaks down. You take it apart and identify that it needs a replacement spring and drive assembly. This is the third time this has occurred in the past six months, and each time the thread on the drive shaft has been stripped. You previously purchased replacement spring and drive assemblies from the manufacturer’s US office, Hektik America Inc., 21 Lincoln St., Chester, Mass., on May 23 and June 17, at a cost of $218.50 each. (The Model 370 Water Stage Manometer is manufactured by Hektik Industries GmbH in Dusseldorf, Germany.) Yesterday you faxed purchase order No. 26019 to the Chester office, requesting immediate shipment of a replacement spring and drive assembly. Today you decide to write to Hektik America Inc., to complain about the repeated failures (you may attribute the cause to any condition you wish, if you feel you need to point out the cause), and to request that the current replacement part be supplied free of charge. Write a letter to customer service.

This is to inform you that, we have been buying your product Hektik Model 370 Water Stage Manometer order No. 26019 since a long. It is unfortunate to inform you that, it is not working up to the mark. We further can not rely on this product, as it stop working at critical moments. It's spring and drive assembly have been exhausted and it needs replacement. It has broke down several times. Unfortunately, we can not continue using this product, as it has severe repercussions on our company. Therefore, it is highly requested to replace this product with a genuine one and free of charge. Otherwise, we will be compelled to change the supplier of this product for our company.

Your's Truly,

Engineering Technologist,
