Lost almost R4000. Rude and unprofessional staff staff

Bought 2 cameras worth R7700. Out 2, 1 was broken. Tried to install and discovered the material is fancy but poor quality. Brought it back. Was asked to pay more to get alternative. Was given 2 instead of 3. When I enquired, they gave me the last, broken though. Blamed me that ot broke when I was installing. Mind you it's a 4g solar camera. They sent a video, saying its internal board had burnt. How does itnburn when it is solar. They are rude, blame, unprofessional and ****s. Dealt with a lady and a guy in Centurion. Lost my almost R4000. Glad I got an alternative place in China mall for the cameras which are even cheaper and of good quality.
