We try to build relationships with all our customers, and we only gain trust by continually providing value and service. An example of this is our relationship with TfL - London Buses. We have been working with London Buses for over ten years. To maintain our relationship, we work closely with all the various entities within London Buses, to help educate them as to what is available and what they need, tailored by feedback from the end users as to what is required from their PA systems. We also provide quick and efficient response to any maintainence issues that arise from the numerous systems we have supplied and fitted. By providing a feedback between end user experience, maintenance issues, and information on latest technologies, we can educate the specifiers to a level of system which is fitting for such large mass transit hubs, but at the appropriate level of cost, affordability and value, without sacrificing the ability of their staff to actually use the PA systems.
