Good for nothing laptop

I bought a Lenovo laptop on the 23-01-2016 at Macro Bloemfontein, the laptop started to give me problems and on the 27-01-2016 and took it back on 28-01-2016. I took the Laptop back but to my amaze of only having had the unit for just four (4) days that I was informed I would have to wait until Tuesday and they will give me feedback. The service at macro Bloemfontein was so bad that I had to call them several time with my money to find out about the progress. I was informed that on their system it was recorded that I was given a call in which I have never received. After 6 working days when I call and held the phone for minutes (still spending my money) they then tell me that the laptop was just sent to the manufactures and I should wait for two to three days until it gets to the manufactures and another 10 working days for an assessment. The waiting is painful enough on its own but for me as a customer to make the run-around it is the poorest level of service I have ever seen at Macro before, I have usually experienced excellent service at Macro but not in this instance, please assist.<br>
