The worst service ever from a store. Really bad!

I bought a PC at Makro Cape Gate. Had it for 2 days and it broke down. Loged a complain (no 13012) and i was send an email telling me it will take 1 to 2 working days to give me an answer. Its been 3 weeks now. If i phone Makro, you never get an answer or i get cut off. Never ever by any electrical equipment from Makro. Please people.
