Terrible Painter and Decorator - MH Harden and Son

I used a painter and decorator in Fokestone by the name of MH Harden and Sons who is on your site. My property was empty and being looked after by an agent. The painter assured me that the job was done beautifully and I stupidly paid him. When the agent went round they sent me pictures of the property and told me it was the worst paint job they had ever seen. I can send the pictures if required. I have been trying to get the painter in to correct his mistakes, he was supposed to go in today and didn’t show up. He kept the keys for three days after finishing the job and has left paint tins at the property. He painted the wrong room (doing the sitting room and not the kitchen) was supposed to paint the ceilings and didn’t. Painted round hooks and a picture frame and over cracks. No cutting in, the old paint colour showed through, damp patches just ignored and left unpainted. None of the curtain poles were taken down. The list is endless. He is now ignoring my emails. People should be warned. I would like to know what redress I have?
