Nokia — nokia 7.1 charging point issue

I have purchase a nokia mobile of series 7.1 of androidone, please find the below details of purchase as:
Model name : nokia 7.1

From the starting date onwards i have an issue with the usage of mobile, it struck every time. On july 7th 2020, there was an issue with charging the device and i have visited the customer care store to resolve it. But my device is under warranty and the customer care executive didn't resolve the charging issue of the device.

Then i have made several calls to the customer care support and i didn't get any response until today. Now the warranty of the device is going to expire next month and the customer care executive is not resolving the issue. Instead of my several calls they only transfer calls from one person to another rather than solving the issue, which is really pathetic.

I have used nokia mobile phones in the past too. And due to its good performance i have bought the product again. But a huge disappointment from you guys for that reason i am never going to buy nokia products as well as never going to recommend it to anyone. I am going to forward this message to all social media accounts so that rest one can see the pathetic product as well as service from you guys.

So disappointed that the dealership and service center have forgotten it is about customer service. I am never going to buy nokia products again and suggest customer support to respect when they are handing over hard earned money.

Please clarify the following queries:
1. Why the customer care executive is not responding for a customer query.
2. If a device is under warranty, then why can't you take the issue and resolve it.

As per my understanding, the hmd global decided to collect more money even if the device is under warranty. This is the worst service which i have received until now from you.

Please revert immediately and do the needful.
