BSNL — Billing harassment

Address:

Gujarat

Sir
I was using broadband before two years on BSNL landline no. [protected] but after some time they were not giving proper service they just go on giving different numbers and names to contact for solving problem. So after some time on may 2011 i did not pay bill. And they stop giving .e service. Now in january2013 this year they came with a bill of about two thousand and scared and abused my family members about putting you in jail and all. So we gave them money. But afterwords again they are giving us bills of 500rs every month which i am not paying because they are not providing any service to me.
Sir please help me out.
