Motorola Solutions — Service center does not handle rectify my warranty related issue

I have about 40 days left on my warrantly on my moto g4 plus phone.. My phone is having an issue regarding the fingerprint sensor and the microphone as both are not working properly. So i approached a lenovo center, but they ask me to pay money for some chrome body and the screen which needs to be repaired. Which is not even damaged. My issue is something else and the solution is all different. If my phone is in a warrantly then its the responsiblity of the company to repair my harware related issue which is covered in the warranty... Please rectify my issue
