For two months my landline connection is dead.i have observed in a year i have merely talked from my bsnl connection 6 months and other six months it remain dead.This is going for last 7 years.every alrernate months the phone is dead.but money is automatically deducted from my ECS scheme.Now i want to stop.my ecs scheme ..when i went to JAdavpur telephone exchange i was told it has been shifted to another place in kamalgazi.Now either i will instruct my bank to stop payment to bsnl.if that is not working i.will withdrew all my money from the account so they can not deduct money .frkm next billing cycle.
