Mahadiscom / Mseb / Msedcl — electricity theft/ incorrect meter reading

I have been getting inflated bills for the last 3 months. I normally pay a general amount of rs 90 every month for energy charges as no one stays at my house in asangaon as it is locked. For the month of june, i got a bill of rs 3600, july - rs 220 and this month rs 1000. This is absolutely ridiculous. This bill cannot come so high as no one stays at my place, there should not be an consumption. Someone seems to be stealing electricity from my meter or mseb are just trying to make a fast buck. I tried calling the contact center, but the are just useless. They said they will correct my bill, but they have not done anything and now it is getting frustrating.
