Icon Property Group (Delft) Poor Service

Good day I have a problem with Icon property group Delft. I have been struggling with this business since June 2021. One of their ex employees have conned me and my sister with selling our property. To make a long story short, I have then made contact with this manager Gary informed he on what Shaun has done, but this thing is dragging I don't get any feedback from Gary been emailing him no replies, when I whatsapp him he would tell me to email him , but still I get no feedback from these people. Their service is poor I just want my money still owing from these people oor at least feedback. This is really draining
