Poor service, Damage goods, Angry customer

So me and my wife decides to buy a new lounge suite end of April 2019. Since the suite was deliver they have collected the 2 seated 4 times whereby complaint was log only twice. Many phone calls which I was diverted to another number still no feedback. The 2 seated has been removed from my home to see what is the problem (this is 3 weeks ago). So I'm keep on calling Bradlows and go to the shop to get feedback. Since the 2 seated is gone we started sitting on the 2 remaining coaches whereby both of them are faulty as well. No I have asked the Branch Manager to either refund me or let me be able to take something else from the floor (again this is 2 weeks ago). Today 20th August 2019 I'm informed that they will collect the two remaining coaches to inspect what the problem is. I'm really frustrated and angry as this will leave me sitting on the floor with my wife, first born and 13 month baby. Is this how I must be treated after this was a cash sale of R30k. If there is anyone that can refer me to someone to assist me on refunding me I will highly appreciate it. The respond from the Branch Manager is that they need to pick up these remaining coaches to take it for inspection then only he can request for me to be refunded and so on. When I went in on buying the items there was no issue on taking my money, now that there are these problem its a hassle to get something out of them.
