@Ameen My connection is directly from BSNL. I had a talk with the BSNL officer who handles FTTH. But he doesnt has much knowledge about this. He only enusres if the connection is running or not. He told eveything is ok from his side. " Upar se hi kuch issue honga". Didnt argue much with him coz he was clueless.
Well there is a silver lining, they wouldnt blame it on the lco anyway now. atleast that part they would skip. Hope it rectifies soon. . In my case they did acknowledge the issue, but didnt know how to rectify it. Since only my lco had this issue and no other lco from the same exchange had any issue whatsover.
