Ibought a laptop ans received a broken laptop from vodacom

I ordered a laptop at vodacom online, last year 7May 2020, i received the laptop but i noticed the next day that a button was loose. I call in at vodacom i told them about the A button that is loose on my laptop, i was told that someone will come and collect the laptop and i will receive a new unbroken laptop. I waited for someone to come but no one came to collect the laptop. I called again the whole of 2020 i called only to be told that this issue will be escalated to a manager and the laptop will be collected. I then told the person i spoke too that i am not going to pay for a broken laptop. I then received a call from collections i told them what's happening, i was told to do an Affidavit and send it to them which i did. I'm still waiting and now it's 1st November 2021 got a collections call again, i was told to forward the Affidavit again which i did. I and not paying for this laptop. Almost 2 years now. KhayaNjomba
