bad services and warranty policies

i bought a laptop from cash crusaders northcliff piazza randburg when i bought i took it home and there was three faults i found 1 was battery second the mini hdmi port was faulty and the third was the wobbly screen.I took it back the next day and the booked it in i got it back 14 days later still with the wobbly screen ..so i made it known to the sales staff that i still find the screen wobbly .. but she told me to take it and check .. but i started doing work on it and yes the screen was wobbly but i needed to do work on the laptop and took it back some time after but still under the warranty period it came back after 14 day still with wobbly screen and i was then upset the manager a mongezi told me that they send it in and they repaired it .. i told him nope im not happy with it but he insisted i take it and test it ..and he left me standing in the store and he disappeared .. i asked the sale person where is he, she said his gone back so i told her to call him .. he came back we continued our discussion and now for the third time he told me test it so i took it and the next day call the head office because it still was not fixed spoke to some adam mohamed and he told me he will get in touch with the store and get back to me he never did i called him back and he told me the regional manager will call me as she is handling the query never heard from them for cpl days so i called him back he was not there and another chap who helped me at head office and told me he will call me back with in the hour well he did and told me the regional manager will call .after some time she did and then all the lies and arguments came out according to her adam closed the query after speaking to the branch which no one informed me about anyways to cut the long story short she said they seen the cctv footage where the manager showed me the hinges and i told her then the footage must have shown that i was showing him that its not correct . but the argument went on .. then she said why did i bring it back the second time after so long i told her i was busy with it and i brought it back loong before the warranty period .. after that she told but the wobbly hinges are not under warranty so i asked her then she should show me where in the terms and condition is there what is under warranty and what isnt , she was looking for all the excuses to get me off ..so now i think i will have to maybe write this off or take it to consumer council and let them mediate between us coz the laptop was 5000.00 rand all i want is that it should be fixed or refunded or give me something same as this
