Default furniture, false adverti*****t and unsatisfactory customer service

We bought a dining table and it was delivered a month ago, upon delivery we picked up some default and few scratches with the dining set. The supplier promised to urgently attend to the matter and two weeks later they came to collect 1 chair and say they will be back to exchange the table. Its over a month and we haven't had anything from them. We cant even celebrate or enjoy the table and by just looking at it on a daily basis, it brings stress and unsatisfactory feeling of buying something with love and end up stating to dislike it. No communication or update on what it is going on. They're gone AWOL.
