R30 000 Laptop problems from Day 1. BAD SERVICE

I am a cinematographer and spend most of my working day behind a PC, editing footage. Looking to upgrade and after hearing nothing but good things about Dells great customer service and amazing PC's, I went and purchased a Dell XPS 15, from incredible connection, over my original choice of a Macbook Pro.<br> <br> Well I have had nothing but endless trouble with my PC from Day 1 and customer support has been pathetic! Over the last 6 months the PC has been in 4 times, for anything between 2 weeks to a month at a time. Even after replacing the motherboard, I am still having problems.<br> <br> I have not only lost business from this huge inconvenience, but I have lost clients! <br> <br> I am so tired of hearing excuses and never again will I purchase a Dell computer, nor will I ever recommend one.<br> <br> I DEMAND A REFUND!
