LAPTOP STOLEN BY AN AGENT OF AI YELLOW

My son had an interview with one of the agents of AI Yellow. He said his name is Johan De Bruyn and his phone number is 0712613715. He said he need to use my son's laptop to upload programs in order for my son to work for AI Africa. From their he gave false addresses. His phone is off. I tried to contact your company but in all google adverts I could not trace a contact number to check agents working for AI Yellow. This is sad. The public should be able to know or check agents you employ. We opened a SAP case. The phone number is not listed on Rica. It is a pre paid number. This person also advertised under Mr Ben on Facebook under Jobs in Brits. He says he stays in Hartebeespoort. Do your company keep track of advertisement as agents? How is it possible that their are no contact numbers for your company available on the internet? How do we check if an agent is legally in your employment? Can you maybe assist with this case in order to assist to get my son's laptop back? How do we know if people is in your employment or act as directors of AI Yellow?
