High everybody,i have taken bsnl broadband home combo ul1350 from two months.my phone number is 03581-258458, 4m dinhata,west bengal.their is a joint(pretty much exposed in air) in my landline connection.bsnl lineman gave me joint wires intentionally to save some wires surrendered by someone.now i face frequent disconnection problem at night(dont know is it for the joints or some network problem).i heard from a bsnl broadband engineer that there should be no cuts or joints in a landline wires for proper broadband connection.so i requested for a replacement of my landline wires at local exchange, but the next thing they do is to call me back and refused to change my wires.what should i do now to change my landline wires.will bsnl ever change my landline wires or i am stuck to it?
