Did anyone experience a defective microphone on the LG Tribute Dynasty?

Had the LG Tribute Dynasty for about 3 weeks. The person I call can't hear me talking. Found out there is defect in the microphone. The manufacturer wants me to send it back, so they can repair it. Did anyone experience this issue? Does the manufacturer do a good job with the repair? Don't want to go through the hassle and have the same issue happen again with the "repaired" phone. Thank you!
