2 computers bought

Bought a gaming and home computer from them in December 2014. The gaming pc went back 4 times staying over for periods of a month at a time and still not working. Home pc went back 2x not reading harddrive. We phoned for our money back but now we are being ignored. Nobody getting back to us. We now have 2 duds that we cannot use. Its a disgrace. They have our money and we have no service
