I am living with three other roommates including the landlord. I am supposed to pay 1/4 of whole utilities. However, the landlord told to another tenant that she would charge differently to each person, based on who used utilities more or less. I think everyone is just using utilities as necessary. The landlord is always saying that she won't pay if it's more than before.
I paid $100 for September and she said she would pay me back in case I paid too much. I've been asking her to show the copy of the original bills to us since Sep, but she's not done yet. Can I reject to pay utilities until she shows me the bills? Also, does the landlord have the right not to pay more than last year and make us cover it?
