Query: What? I Can't Hear You!

Like other's who have posted here, my phone is going back to the store today. After having nearly every caller tell me that they couldn't hear me, and finding no way to adjust the volume any louder, I went out and bought a different phone. Also, because of the design of the keypad, would constantly brush the keys against my face and inadvertantly hang up on callers. Good idea, bad design.
