Dishonest business owner - be careful

Dishonest business owner. He was going to do simple work in my home in exchange for work I did for him & products he requested. He took a wooden plank out the cupboard "so it could breathe", and has left it there. I chased for months for him to complete this, it is now a year later & I told him to pay for the work I did instead, so that the energy exchange is even & I will consider it closed. He of course agreed within 1 minute, and of course weeks are flying by with no responses. Dishonest - certainly would not allow him into your home.
