Bharat Sanchar Nigam [BSNL] — full network issue

Address:

Bankura, West Bengal, 722101

Network dismissing for 2 hrs at night from three days, sometimes internet is not working and outgoing calls are also not going. I'm from bankura, west bengal. Don't know what type of problem it is but very irritating and frustrating. Please fix this as soon as possible. Tried many solutions like turning airplane mode, changing phones, changing slots, but it's a major network problem so pls fix this issue...
