Very disappointing service -Makro

I am highly disappointed with Makro Customer Service, I booked in my laptop on the 20th of April, keep in mind it was just over a month old, it had a blank screen problem, fair enough it is booked in and still to this date no word regarding my laptop. I work on my laptop for an income, so this means now a full month I have no income because Makro's technicians can't fix a simple blank screen error???? At this point I just want my money back and I will take my business somewhere else.
