Bharat Sanchar Nigam [BSNL] — non working of phone line & broadband

Address:

Kolkata, West Bengal, 700006

Dear sir/mam,

I have been using a bsnl landline for more than 4 years now, however in the last 7 to 8 months the service has become really bad. The phone line works only for 15 days in a month.
The technicians mr shyam lal kohar & mr amit kumar promise to help us every time after restarting the connection, but after 15 days the phone & internet both stop working for another 7 days.
The phone and the internet are not working for 1 month now. I would like to surrender my connection and get a refund
My number is [protected] - kolkata
