False pretence

We're selling our property privately, and we received a call from Engel & Volkers in Potchefstroom requesting to show it to two serious out-of-town buyers. Although we don't want to use estate agents because they tend to lie, we believed the agent. On arrival, neither of the two "Buyers" was present, and it was clear that the agent and owner of the Potchefstroom branch were misleading us into viewing the property just to see it themselves. This is highly unprofessional and shows poor character by blatantly lying like this. Can Engel & Volkers' head office please send these guys on an ethical course, as they really put your name in a very bad light?
