Nokia India — nokia 6.1 plus charging port issue and vibration problem.

I bought nokia phone 6.1 plus. My phone is under the warranty. From last 3 months mobiles charging port is not working and mobile is not charging properly. I visit service center in trivandrum but service is taking 10-15 working day to resolve my problem. My phone status pending for changing charging port it's take a longer time. They are saying that the part is not available its yet to come and all stuffs and my mobile is there with them and its been more than 10 days and the problem is still not resolved. Really not satisfied with the service that nokia is providing to their customers.
