Typically this happens when a user tries to renew after their original end-date has passed. Go ahead and select the option to renew at a new address, but use the address you are living at on the renewal application. This will tell us to keep you at the same address.
If your end date has expired before your roommates, your bill will not be evenly divided. You should check to make sure you received the right portion of your utilities. If you notice a bill was not accurately divided, contact us and we will work to fix it for you!
