Motorola Mobility — Get damaged product

Hello sir
I bought a mobile moto E5 plus1 year later. That's IMEI no is [protected]. Mobile is complete bad product which i got. I went around 5 to 6 times in care for recover that product. I got mic, speaker problem again and again. Recently 1 month later I went to motorola care for recover its speaker but they didn't respond. They always told again and again that part will come then we will contact you. I get my mobile today 1 month later now my warranty is over and now my mic is not working. So I faced problems in that my full year from my mobile that my speaker and mic is not working good. So please kindly changed my mobile.
Thank you
