Damaged Laptop

I bought a Laptop at the Game store Makhado/Louistrichardt on the 30th December 2017.When I had to start using it, I realized it had a damage on the buttons, infact they were peeling out.I returned it to the store on 2 January 2018.Only after 3 days of buying it.They told me they have to book it for repair,they called their repair center whilst I was there and told me they were closed and I had to come back the next day with the item.I went back again on the 3rd January 2018,they could not help me and told me to come back the next day.on the 4th January 2018 I returned and they booked it for repair and they told me it maight take 3 weeks at repair centre.On the 12 January 2018 I received an SMS to inform me that my item was ready for collection,i went there only to find that no repair was done.The manager told me he has to call the repair center again and that's when I started to have an argument because I wanted a refund or new item.Im very much disappointed because they gave me a very pathetic service up today.The manager told me to come back on Monday 15.01.2018 because it was Friday and I didn't understand it because Game store do open during the weekend.
