Dear sir/mam,
We are from janta flats, gtb enclave flat no. 1960 to 1965, we having issue with sewer block from the last 4 months back but till the time there is no any positive response we get from the delhi jal board, every time we log a complaint against flats no mention above as per discussion with the delhi jal board official they said this is not our issue because of pump is not working on time that's why this issue is coming on the day to day, if there is proper pump is working regularly this issue will not come again and sewer will working fine,
Kindly take a look on it with humble request.
