Hello, my headset (Logitech H600 /wireless headset - black) was purchased on 4/1 and delivered on 4/8/2020. It was purchased via Google Shopping/Best Buy on order (G-SHP-1412-27-****). The sound is VERY low now - leaving me unable to hear customers, and the mute button rarely works...which has now caused issues at work. I have kept it on a desk, so it has absolutely no physical or liquid damage. How can I get this replaced? Thank you, Natalie User's recommendation: They don’t respond.
