I'll post a link at the end of this message for you to check out. You'll be able to submit a claim ticket and a support specialist will reach out to you to get this issue resolved. We apologize for the inconvenience, have a great day. -Ricky | Logitech. https://support.logi.com/hc/en-us/articles/360025080753-Warranty-Logitech-Wireless-Wave-Combo-MK550
