Incredible Connection is USELESS

I purchased a new laptop in December, TWO days later it overheated and was replaced. Six months down the line more issues with the new laptop, but as I was overseas I could only return it in August. They sent it in for the LCD screen to be replaced. FOUR weeks later it returns and my entire harddrive and programs have been wiped. No explanation, just constant excuses for their negligence. It is my source of income and they just couldn't give a s**t! This has been ongoing since August 30th, appalling and pathetic!
