Galaxy S5 microphone issue

I went round and round with Samsung and my provider (At&T) yesterday concerning the microphone issue with the Galaxy S5 phones. (They're equally well aware that the microphone is defective.) My question to you guys is..... If any of you have had your mics replaced/repaired could you please share who did the work for you, and did the work come with any guarantee? Samsung will only guarantee that "the mic was working when we shipped It.
