MAKRO LAPTOP POLICY THAT WAS NEVER HIGHLIGHTED INSTORE OR GIVEN TO ME

I bought a Lenovo laptop on sale at Makro Alberton12/04/2021. The laptop never worked properly, freezing every time I typed a Word document. I tried to sort this out, reloading the Microsoft package a few times, but to no avail. In the end, I took the laptop back to Makro Woodmead on 23/05/2021 requesting either another laptop or my money back, as this machine is faulty. I was told that I have to wait TWO WEEKS in order for Makro/Lenovo to asses this laptop. I was also told if I wanted it quicker to take in into the Lenovo workshop myself. I was also shown a board which states you have 2 weeks to bring the item back for a refund, otherwise the waiting period rules. This board with the rules is no where in the store, so I did not know I could return this item within 2 weeks. The manager Kobus was quite rude, whilst admitting that he did not know anything about laptops, told me I don't want the machine because it is too slow. I noted that the laptop has never worked properly from day one and I want a refund. He stated that he will get another person (who works for another brand) to check the laptop on Monday morning, as I advised I needed this laptop for my job. This is really not the service level I expected. Nowhere in the store are the terms and conditions displayed in the IT section, so this is totally unacceptable. I left the store with Kobus and the young assistant opening the laptop and doing who knows what with it. Very Very upset at this treatment and I will not buy from them again. I felt like I had to justify bringing back something that never worked from the outset. As my sister explained, we tried to load and reload the software in the hope that it would work but this never happened. BAD SERVICE ALL ROUND
