Camera installation that does not work

Outdoor CCTV was installed at home in late 2013. It didn't work properly and the customer service agent (Riaan) promised to get it working properly. I withheld the second 50%. Weeks passed, no response from him despite repeated calls. I then I found he'd left so I physically went to Chubb's (EXTREMELY CUSTOMER UNFRIENDLY) offices in Milnerton. I met Bradley Waugh, head of technical who promised to resolve. Once again, weeks passed by waiting, even after repeated telephone calls to Bradley. He eventually came to house (about 9 months after camera was fitted) & indicated that it was a supplier issue. This annoyed me as i paid Chubb not the supplier. I never heard from Bradley again. Months passed (I was away from SA, my house unwatched by a camera I'd paid to watch it!) and when I returned I called Bradley who had also now left Chubb. I once again went to Chubb's offices to hunt down someone to deal with. Found Adrian Theron, and explained this and other problems. He took notes and promised to resolve. Weeks later I had heard nothing so called him- he couldn't recall the event. Eventually techie came, couldn't fix. Back to Adrian to resolve. Weeks later I am still waiting for Adrian
