A:
I've been buying Logitech for over 15 years. I've never had an issue with their products. Sorry you've had a bad experience. I searched your product and found this: http://support.logitech.com/en_us/product/wireless-mouse-m325 There is a help button towards the bottom that takes you to this link: http://www.logitech.com/en-us/contact
I recommend registering with their site if you haven't already, and hopefully you registered the product itself. That makes access to their customer support easier as well. Again, I hope you find resolution. I own at least 10 Logitech products and have never had a product fail. Good luck.
