Theft case

I went home for two good weeks only to find my play station ******, there's no sign of penetration which proves that a key was used to open my door, there was a painting construction going on yet after several attempts of reporting this to the building managers apparently there's nothing they can do, we have WhatsApp group which i believe if my case was reported someone might be of assistance, they did not even bother with searching from cctv from lifts nothing, I'm really disappointed at Absa main towers building managers
