Estate agent claims to be Principal of Homefinders Estate Agency has husband working as both estate agent and handyman at RandL kitchens

Estate agent claims to be Principal of Homefinders Estate Agency has husband working as both estate agent and handyman at RandL kitchens. Has various tenants that are electricians, plumbers and professional cleaners. Refuses to increase their rent and apparently 'robs Peter to pay Paul'. Removes 'old taps' from this property and installs them in next?
