That's called a "warranty" and its free for the time period involved. Whatever reason you posted, understand any after the sale advice or support costs a company. They provide initial support and depending on the product maybe even more than expected, but again it's all on a time table. Most after the warranty is expired provide support by some forum or knowledge base via a "support website". That in turn resolves many typical issues usually in the setup or use of product plus any lost s/w, docs, etc.. Of course, if you have a hardware problem its actually broke, then even here the warranty depending, details cover/explain it. Items that are true manufacturing defects/faults are posted there as well. Alas, if you have a popular item, sometimes any support would overwhelm it so gauge how that affects you, but could be addressed better as time passes.
As someone who is perpetually getting into trouble with my computer I am constantly looking for help and it is clear that the major players in the computer world have discovered a way to avoid contact with those who keep them in a job, us, the customers by creating Forums. I have a lot to thank those selfless folk who spend their free time helping the incompetent such as myself but surely its time that the big companies such as Windows, BT and many others actually set up a direct line to themselves ready to dispense advice!
