Bad Customer Service

I bought a Kitchen Unit Set from Lewis in Claremont before the store closed in June. A week later i called the store to report the issue i had with the top of the kitchen unit and i spoke to Debbie who promised to attend to the issue immediately. Debbie called me four times after the initial complaint and every time i would tell her the same thing and every time she would promise to get someone to call me but nothing and in the same sentence she would remind me about the payment BUT how do you pay for a product you are not happy about that was my question to her and she suggested that she will send the driver to pick the kitchen unit while they are trying to resolve the issue which never happened. I received a call from David the driver who then went to my place to look at the Kitchen Unit and took pictures of the things i was complaining about, David phoned the store and Samantha phoned him back and spoke to me she also is not interested in sorting out the issue she is maintaining that the issue will not be resolved if the account is in arrears and also told me that they will take the kitchen unit back if i don't pay the arrears with an arrogant tone after i have also mentioned to her that i have complained about this 4 times and no one has responded all they want is money and don't care about the issues i have with regards to the product i bought from them.
