[ can list 50 - 100 more numbers. ]

Issues : network bars shows full. But as soon as any call is made or start using the internet, network drop to only 1 bar or no service (Many times).

Location : [ area is literally in middle of the city. ] shivam park street no. 4, behind nagrik sahkari bank. Near raiya chowkdi, 150 feet ring road, rajkot - 360005. [ link : https://goo.gl/maps/qja3LToPDSB31QQB6 ]

Current situation : internet speed is like opening google.com takes 5 to 10 minutes. (Average). Sending simple & short whatsapp messages may take 10 to 30 minutes.

Issue since :
Past 1 year.
With last july-sept (2019) youtube video @ quality of 240p was not playing continuously.
Oct-dec (2019), internet started being even slower day by day.
Jan-apr (2020), call drops started.
May-june (2020), "no service" very frequently for 30 seconds to 2 minutes.
July-aug (2020), "no service" very frequently for 5 minutes to 2.5 hours.

Already tried following solutions (Multiple times) (Suggested by jio care) :
1). Sim card in volte compatible handset on sim slot 1.
2). Apn setting correct, device rebooted multiple times.
3). Tried multiple handsets to verify if it's a handset issue. (No issue with handset. Problem persists on all devices).
4). Contacted jio care chat - not much help. Refusal to create service requests on multiple occasions.
5). Jio care : same pre-typed response that we're trying to provide better services to all the users. [ no action. ]

Note :
Issue reduces post 11:45 pm to 5:30 am. During which use case is not much.
Also pointless to pay for these long durations of equivalent to quarters & years.
For such a poor service & arrogant replies. And to mention denials of service request creation.

Even appellate authority are taking no action.
