I have a bsnl broadband plan 675/- per month. From 28th March 2016, my connection is not working properly. I have complaint through 198 but no action has been taken yet. Someone from bsnl calls me and asks me whether it is working or not. Bt still now its not been working. I have complain through 1504 and spoke with their customer care workers they assured me it will be taken care of within 24hrs. I have called a minimum 30 times on their number regarding my broadbank link which is not stable.Today is 10th April 2016 still my connection is not working properly. I want the line to be fixed immediately and want a recession of the bill also.
