Awful, negligent service from staff!

Absolutely horrible service from Incredible Connection! First of all, they sell me a used and returned Macbook and neglect to inform me of this prior to the sale, and now for the past two weeks I have been struggling to get a new, sealed and properly working Macbook from them. <br> <br> I have filed a complaint via email, on their website and via telephone, and all they did was pass it back to the branch, and they still have not been able to resolve the matter there satisfactorily and refuse to give me a number for their head office. I was promised two days ago that the branch or regional manager would phone me back - after two weeks of going to the store without any results already. This has cost me so much unnecessary time, money and inconvenience. And it all comes down to a misleading salesperson at the end of the day. And now they lack the efficiency, competency or decency to resolve the matter and give a new computer. So how many more complaints do I have to file for them to resolve the matter at all? This is just ridiculous and unacceptable!
