I am trying to sell my flat, I have instructed an agent on sole agency terms and signed a contract. The agent has keys for viewings as the flat is not used very often at the moment.
The concierge of the building also has a set of keys, all the apartment front doors and common areas are being painted so they need keys for the decorators.
There is a man that lives in the building who runs his own estate agency business. He called me the other day trying to encourage me to use him instead of the agent I have already appointed. I said no, sorry, have already signed up with someone else.
I found out today that he has somehow managed to get the keys from concierge and taken someone for a viewing of my flat.
I have been spitting feathers over this and already gone ballistic at concierge over the phone. What else can I do?
