Nokia India — nokia 5.1 plus charging port issue

Address:

Kolkata, West Bengal

Regarding charging port issues they told the common thing liquid damaged.
Even port is losses and didn't connect properly. After solving the charging port from kolkata bagbazar service center with payment faced the same problem after 3 months. But now another care located at esplanade, kolkata told adhesive use for fixing the phone isn't a othorized glue. So it doesn't come under warranty. Device wasn't repair from outside. So the adhesive is given from care. But is not approved at another. So warranty service is not available although repair from authorise care. So why the warranty is given? Is any solution available or this type of business is going on...
