If you have a product that is having problems, call the manufacturer! If you don't get the answer you want, keep calling and asking for their custome care or customer service department. Keep going up the ladder at the company...they WILL help you! They want their customers to be happy and they want to sell good products- thats why they are in business. The store where you bought it really doesn't matter.
I bought a new HP laptop last year and had a problem a few months later. Sent it back to HP, they fixed the problem, did some checking and found other issues that I wasn't even aware of..fixed them all at no charge to me. They did a great job of Customer care.
Good luck!
