No service

Nashua Worcester, Western Cape, installed a camera system and telephone system at our school. We are on a 5 year contract with them. I don't think there has been one month without some sort or problem with the systems, especially the camera system. It is constantly not working - not due to loadshedding. There are never any technicians available to support us or sort out the problems. I am looking for ways to end the contract as soon as possible. Will never do business with them again.
