We have recently had 7 cold water machines installed into our new building in Norwich . In addition to the good service received from yourself, I would particularly praise your engineer on the installation. Despite being last in the chain following the installation of a number of vending machines which created several problems, he adopted the stance of "that's no problem" and then proceeded to delivery exactly what he had promised.
It was a welcome change from several of the previous engineer's attitudes and was an excellent advertisement for your company.
