Bad service from Info Prop

I bought a property in Umdloti KZN through Bonnie Stewart who goes under the Info Prop banner. Her commission for this deal was around R150000 yet she would not contact the seller to give me access to measure areas for furniture. When I pressed her on this issue she hung up in mid call and did not take my calls again. When the transfer went through she left the keys at security and simply sent a whatsapp message saying she had car trouble and could not meet me at the place for a handover. General attitude was bad and I would avoid her in future.
