Business Notebooks

Less then 2 years ago I spent $2000 on the HP Spectre, within these 2 years I use this laptop minimally (3 times a week maybe) and somehow it has managed to breakdown twice. It shows an error page asking me to boot it and won’t allow me to do anything on it. Once it was in the middle of a business trip, the other time I was in the middle of studying for an exam, it’s hard to describe how inconvenient it was and I nearly lost a client/failed an exam because of this. Currently it is not working and after talking to customer service they arranged to have it repaired which will mean I will be without a computer for a few days and they said that the data on my computer could be wiped! They even told me it was MY responsibility to back it up regularly to ensure that i don’t lose my data. I don’t spend $2,000 on a computer for it to break down twice in less then 2 years and then have some rep tell me it’s my fault that I didn’t expect their top of the line product to break down regularly and should’ve made a backup. They didn’t offer an extension on the warranty or anything, just said that it’s my problem now because I’ve bought it and that’s what happens when you buy a notebook. I’ve been a fan of HP for a while and recommended their products but I swear I will NEVER buy anything from HP ever again and recommend to everyone around me to do the same. I just want to know where I could send a formal complaint to so I can explain what happened and why they’re losing a life time customer.
