Why keep "waiting" for more bad service?

<p>I purchaced a cupboard (which requires in-home assembly by Lewis), just over two months ago. The first assemly took place soon after it was delivered... but upon completion the cupboard was damaged from the assembly.</p> <p> </p> <p>I voiced my dissatisfaction immediately but I had to continue to wait from one day to the next for them to come replace it. I waited over three weeks, but upon delivery of the new cupboard, the Lewis employee doing the assembly noticed that the parts delivered were in a worse condition than the one they had to replace. I was instructed to insist on another one to be delivered because of the poor condition.... Third time's the charm, right?</p> <p> </p> <p>Now it is the third time I am waiting for assembly. Each time I contact Lewis (and go to the store to address the matter with the manager in person), I am promised each time that it would take place either on the same day or the following day. As past experience has taught me it wouldn't happen as they promised, I give them the benefit of the doubt - perhaps they would try harder seeing that they have a bad reputation as it is with all my complaints... but no.</p> <p> </p> <p>The whole process from the initial purchase to now is going into the third month now - and they have received payments already, by the way.</p> <p> </p> <p>Why am I even waiting on them to give me even more empty promises and bad service? </p>
