Realme — Service

I gave my phone to the service center of realme to make my phone on 1st july 2020. He told me that in the evening you will be called and told what is the problem with your phone and how much time it will take to make it but i did not get a call from the service center. After that i went 2 more times i called the service center very often but i always used to get the answer that you will get a call from us i also called in the company of realme many times but i did not get any help from that either
And when i called the service center again today, he told me that your phone will not work, please come and take your phone. I want to know why my phone will not be made when my phone is in the guarantee period and if my phone was not made so why make me wait for 1 month. Please help me nobody listens to me neither the company nor the service center.
