Mahadiscom / Mseb / Msedcl — high bill for may & june 2019

Address:

bldg 19, flat 204, Kh4 Celebration C.H.S, Near Vastu Vihar, Sector 17, Kharghar, Mumbai City, Maharashtra, 410210

My consumer number is[protected] and
Billing unit 4795:Kharghar S/DN.
My average electric bill is around Rs 1000 to Rs 1200 (consumption unit 100-200 units per month) but for May 2019 & June 2019 it has skyrocketed to Rs 5, 600 & 11470 (Consumption Units 396 & 525 respectively) which was shocking.
