Query: can't turn it off

I was very happy with this product for about a month. Much more satisfactory than the Motorola bluetooth ear piece I previously had. To turn it off, you have to depress the microphone arm. It just keeps springing back out and therefore turns back on. This means I cannot transfer a call to my cell phone when I arrive at my destination. The battery won't stay charged as long either. I have jury-rigged it for the moment by jamming a stick in with the microphone arm, but this is ridiculous. I will be returning it to Amazon shortly.
