Legal Question in Technology Law in California

The time period depends upon the agreement with the company you bought it from.

If the need that you have is not being fulfilled and you expressed that need at the time of your purchase or if the item was simply not what you ordered, start with the vendor as most businesses are interested in pleasing their customers. Speak with a manager and let them know your concerns. Give them the opportunity to do the right thing. However, should that fail, depending upon the situation, you may also have recourse through your credit card company.
