Never buying from Essops Boksburg Rand Value mart again

Bought a couch at Essops home Boksburg in the Color Grey , They decided to deliver another colour in Beige and even on the invoice they scratched out the color grey and wrote Beige in pen ,nobody bothered to call and inform me first before delivering the couch to see if I would be interested in a change of colour , I took the couch in regardless and that was the biggest mistake that I made. After the men assembled the couch and had left ,I noticed one piece of the couch was faulty and when I contacted Kim (The sales person who sold me the couch )2 weeks ago she said they would look into the matter. Till today I am sitting with a couch that I am not happy with and cannot even use because the damage is visible . The quality is also bad ,when you sit on the couch it makes squicky sounds as well and the couch is not strong at all and does not worth the R30 000 that I paid.
