Makro shocking service

I think there service is shocking . I ordered laptop online , they delivered next day that was great. Thanks for that. That was November. I used it for little bit , I logged a return on 1 st January cuz my screen was blank. I could turn on but blank and it made huge noise. On the 6th of January I was still waiting for someone to collect it. I also stated how urgent it was , as I needed to start work with it . I called and after long I finally got someone to come and collect on the 7th. Today is the 26th and I still have no response, I have phoned everyday. Firstly after 1 full week of phoning , I phoned the store and they then got the IT guy to call me. He said there is nothing wrong with ur computer and said they will send back next day. Then I got a phone call to say it was the wrong laptop they tested, mine will have t9 be sent in to be repaired. I'm still waiting. If you read the online terms and conditions it says if it is within 6 months replace , repair or refund. Mine wasn't even two months . I told them I had missed a full week of work and I was gonna loose my job if I didn't have a laptop. It seems like they don't care. I'm sitting still without one. Can't they just replace my laptop.

Because of someone else's lack of work ethics, I must loose my work. Who's gonna pay me ? I'm just shocked st the service.
