Complaint about the Bad Quality of Goods from Lewis Store

I bought new Coaches from Lewis Stores in Khayelitsha Cape Town on 21st December 2018. The Delivery was done on 11th January 2019, the Sofa was not fit for purpose and not in good quality/shape. I reported that matter to Lewis on 15 January 2019 to Ms. Bongi and Josephine our Sales Persons in Khayelitsha who promised for fixing the problem on the Sofa immediately. I had to make more than 15 calls for them to send poeple to fetch the Sofa at home in Middledrift in the Eastern Cape. They only came to fetch the Sofa for Repair/Fixing on the 11 January 2021.The Employees who came to fetch the Sofa confessed that the Sofa was on Display when Sold to us. Meaning that this Couches/Sofa was a Second Hand and not a Brand New Product/Couches. They return the Sofa on the 16 February 2021, and at this time the Sofa had a Scratch on it. It looks like I will continue to complain to Lewis about this Couch/Sofa as nothing is happening. The White Manager from Lewis came to to my house and also promised to Fix this problem, up now no assistance is forthcoming.
