Brymac Furniture and Cabinates

I employed this cabinet maker to build a cabinet in my kitchen , after 5-8 months finally came back with a unit that does not fit , doors don't close now, varnish is lifting of the top of the unit around the sink, 1 unit is 1 inch off the floor because cabinet maker did not measure it right,doors are not made to my design , have tried contacted this person but refuses to answer, very poor workmanship
