Failing to service paid up clients

Good day, So yesterday i get a call from an Andre at lewis in Alberton stating that they will be contacting the furniture doctor where my lounge suite is and will deliver it when done, which was as per Andre yesterday. Later on i get a call from the store manager stating my lounge suite has arrived and they not happy with the way it has been fixed so they sent it back. Now my question is this. The people Lewis is using to fix that lounge suite is clearly useless as they keep messing up those couches worse than what it went in for repairs. Now i want to know what do i do. When i get this lounge suite back will it be in a condition i paid for it or worse that after a few month i must go through this ordeal again. Also taking into consideration that my warranty expires in Oct this year. If this lounge suite comes back and its not fixed to my satisfaction Lewis will compensate me for it and ill find out how i go about it to ensure i get my money back. This is really not fair and after we paid the account in full what if we decided to say **** their account you would have taken joy in blacklisting me but now the ball is in your court and this is what is done to paying customers. Ya'll must be ashamed of how ya'll treat people, really, i know that ya'll don't really care what we post on hello peter but ya'll need to really work on how you treat people who pays.
