We have been staying as tenants since 3 yrs. The landlord uses a portion beside ours and both portions have common electric meter. We were unaware of this and were paying the total bill. Whenever it used to be huge, we used to ask the landlord but she used to bluff us that only we are using it. On the whole she did a fraud of 25000/- INR. How can we get back our money? There is no lease agreement.
