bad service and bad quality

I bought a corner couch , 8 chairs and a side table in January paid about +70k . The service in the store was so amazing Sthembiso assisted us. Everything was bought cash. We received the goods and nothing was unpacked by the couriers we assembled the items our self's. The side table was chipped and unfortunately i couldn't inform the store that time as i had other things on my mind. The couch has a lamb it didn't work since day one. On the 20 May i went to the store luckily Sthe was there i informed him about the experience that i had , he said my things are still under guarantee and he will send the query to Head office. The next day he informed me that the matter was reported and Kutlwano will assist me .After few days i didn't receive anything from them i then called the store they gave me head office number i then got the chance to speak to Kutlwano , Kutlwano said the matter will be sorted out by Lerato he even told her while i was on the line . Lerato didnt take the matter serious with me the next week i called head office again i asked for Lerato , her reply was she was never informed about the query and funny enough i was on the line when the told her about my query, she said she will call me back she didn't bother calling me back. I called head office the next day which was the 11th June 2024 luckily Kutlwano was there he was shocked that the matter was never sorted he send me a query ticket on the 12 June 2024 . Sadly the matter has not being resolved till now. The couch inches are so week. Not even a call to apologies
