B. E. S. T. Undertaking — high bill customer[protected]

I would like to lodge a complaint on the extremely high bill for the months february march & april 2020 as the property has been empty and can not understand why the bills are so high. This electric meter is installed in my flat at 74 venus apartments, altamount road, mumbai 400026. This property is used from time to time and the reason for my complaint is that it’s been empty so how could the consumption of electricity be so to warrant a bill of rs3400 for the month of april. I believe bills are just being raised randomly and i would like you to kindly investigate and revert please.
Thank you
Kindregards
