Delhi Jal Board — Regarding faulty billing

Address:

New Delhi, Delhi, 110065

Refer djb bill no.[protected] dtd 18.11.2015.As per new regulations consumers whose monthly consumption is less than 20 kls. Will not be levied any charges. Here my consumption is 15 kls for 58 days which is very much in stipulated exemption limits of less than 20 kls per month. Then how i have been levied charges of 28/- rupees.I should get full waiver of rupees 428/- as i cannot be levied any charges as per new rules of govt. Of delhi.Hence i should be exempted and my bill dtd. 18.11.2015 should be rectified.Thanks
