Welcome to Android Central! That sounds frustrating. When you're on the phone with people, do they have trouble hearing you only if you're using the phone normally (i.e., without a headset)? What happens if you use speakerphone, or a wired or Bluetooth headset? If that all works fine, then it narrows the problem down to the phone mic (the one by your mouth). If people can't hear you regardless of what you use, then it's probably an issue with the phone's firmware.
Regarding the problems with trying to get a replacement--unfortunately, that's the way it goes sometimes. 28 days is actually a pretty generous return window for a phone retailer--most major wireless stores give you 2 weeks. If Samsung is giving you the runaround, you need to keep escalating and asking for a supervisor. Don't accept what a low-level agent tells you as final. Tell them that they returned the phone to you in a persistently unusable condition, and that it should still be fixed or replaced under warranty. Ask for someone else you can help you. Keep your tone calm and pleasant but firm--don't let your emotions get the best of you. Don't make any threats (like lawsuits, Better Business Bureau reports, etc.) because those rarely get you anything except a hangup. Good luck!
