No responsibility taken even when immediately addressed

I used the furniture removal company on 1 December 2019. On the day of the move, my son put an object down in his room to move something into the lounge. 30 seconds later when he returned, it was gone (the movers were just in there). He immediately asked the movers if they knew where it was and they said no and obviously because you can not accuse people or check their pockets we had to accept it and hoped that it was somewhere between things in the move. Once it was established that the object definitely was taken (and asking them a second time), I phoned the Company to investigate. All I got advised the next day is that the movers know nothing about this. Therefore, if you don't hold on to every small thing on your body, it will go missing! So I paid R3500 for the move and an additional R1400 for the object that was taken. Completely appalled!
