Tenant utility bill question

[Pratima Ulagadde]

Tenant does not want to pay utility charges till statement shows her date of occupancy. The utility statement has meter readings backdated 1.5 mths as it comes from the power company. Utility statements are on a rolling basis in my condominium For ex. The utility statement for the month of June that comes out on July 1st, has meter readings from 04/15- 05/15.But it also has other items which are current to June like common area electric, internet fee, utility billing fee etc. Till now all tenants have paid their utility bill irrespective of what the meter readings dates are. What should I do?
