Incredible Connection doesnt even have the decency to respond to email about faulty laptop bought.

I recently bought a Acer A315 laptop from them . from day one it has been incredibly slow and there is nothing even saved on it. it takes about 15 min to turn the laptop on alone. I have emailed them about either replacing it or even just repairing it as something is defiantly wrong with it however no response ! you do not even have the decency to respond to an email yet you want your customers to keep coming back to you. Your prices are generally higher than other places but you don't even provide a good service so what are we paying for ?
