Bangalore Electricity Supply Company Limited [BESCOM] — we are unable to operate bore well as the 3 phase voltage is only 350v and not 440v

Address:

Bangalore, Karnataka, 560016

Since nov 18, 2017 we are not able to run our borewell motor as the voltage is only 350v and due to this a couple of houses are also facing the issue. When complained about this, they told they will look into it resolve asap. But the responsible person sampangi is least bothered and is not even responding to our calls. Is there any one to whom this issue can be escalated as the problem seems to very serious.
