Very Bad Service from Bradlows Promenade

In 2019 i bough a Tennessee 4 piece Lounge suite leather at Mitchells plain Promenade. In 2020 i went into bradlows to complain about the couch seat that was sagging and was told that a call will be logged. In March 2020 level 5 lockdown happen and I understood that nothing could be done. When the lockdown was relaxed i went into bradlows again only to find out that call was never logged but i was give a lame excuse by the sales lady. She tried to log this call again in 2021 January but without telling me that the warranty would not pay and they came to fetch the 3 seater. After numerous call and whatsapp chats i was told the amount that i need to pay is 5000 to fix the 3seater. The 3 seater was delivered back to my house. I went back to them again and explained why i feel that my warranty should be taken into account because of the lockdown they could not fetch the seater and nothing could be done. Because when I first complained the lounge was still under warranty. They came back to fetch the 3 seater again only to be told that i must pay over 9000 and when i ask the manager why the amount jumped from 5000 to 0ver 9000 i was told that i was never quoted 5000. I am a very unhappy customer. I have even gone back to the sales lady to get contact numbers for the area manager but she just dismiss me. She got my sale but now there is a problem to be solved and she just plea the firth. Now they want to bring back my 3 seater without fixing the problem. I would think because this happen during lockdown my warranty would be extended.
