Makro sell faulty itmes

On 1 Feb 2022 I purchased a bicycle online from Makro. I had to call up and down to get an update on my order until I finally got through to the Bloemfontein Store where I was told they were waiting for stock, this was a very unpleasant experience as I was send from pillar to post. The item eventually arrived on 4 Feb 2022, I only assembled it on Sunday 6 Feb 2022 and on this day my son started riding it only to find out the brakes are not working. This morning I saw you can request a return online so I logged a return request for the item and followed all the necessary steps until it was successfully captured on the Makro website, I even got a e-mail confirmation. I now called the call centre for an update on this and the lady I spoke with couldn't pick this up and told me I must return the item to the store. why do they have a process in place where a faulty item can be collected if I have to take it back myself? with what transport? I bought it online because I don't have the luxury to drive to a Makro store. at this point I asked for a supervisor as I now want my money back, I won't pay for a faulty item. the lady dropped the phone on me. I REGRET BUYING FROM MAKRO
