Demoralizing service

Bad bad service from Acer through Makro. Bought an Acer core i7 laptop in September, took it already for it to be looked at on the 14th of November because it was too slow to process, got a call on the 18th from its customer service, even today the 7th of December the laptop is not fixed. "Apparently" the wrong part was ordered for it to be fixed. No communication whatsoever from them, I only get lame responses from Makro when I call. I am so ****ed really.
