Don't waste your money on Iron Curtain Security

I had 2 CCTV cameras installed for a private propery in Tokai August 2017 for about R 22,000. According to my tenant and my son who lives in the main house the one camera stopped working in April 2018 while I was overseas. I got back beginning of June 2018 and reported the fault. After 2 weeks they sent 2 technicians, and after inspecting they said one of the two network switches was faulty but was still under guarantee. They said the other switch was fine but they still would like to take it to make sure. The next thing, I get an account from Iron Curtain for approx. R 1,277 to replace the two units. I obviously queried this account being under guarantee for one thing and the 2nd unit not being faulty. 1 month later they send another 2 technicians and they confirmed with me that there were still guarantees in place. They also promised that the cameras would be up and running within the next few days. Now here we are 2 months later and they still haven't fixed the problem. There was an attempted burglary and access gained by 2 men trying to lift off our driveway gate from the rails, which proved to be too heavy, crashed to the ground and woke everyone up, but the cameras and the connected alarms were not working to warn us of the incoming intruders
