Bad service by Lewis stores

I bought a dining room suite at Lewis Stores Mams Mall last week Friday. The table top and the stand are separate entities that had to be fastened together with *****s. Apart from the fact that they delivered at night, the table was not tightly fastened.Either the *****s were too small or the guy just didn't care. I made them aware of my dissatisfaction and they promised to rectify their mistake but till now they haven't showed up. Now I'm stuck with a table that tips over to one side.
