<prompt> Human: So I logged in to check my rent, and pay it today. Its due the 2nd of every month. Always goes fine, today it wouldnt let me pay until I paid my account balance off. Fine I thought, whatever its 11.33. I paid it, then it wanted me to pay 22.68, and then 45 and now 90. Total requested is over 850 for a bill they didnt even give a description for. I have never been late on a single bill in my life. 100 on time according to both Transunion and Equifax. They never sent me a bill in the mail, never sent an email, never sent a notification. Just shows up when I go to pay my rent today. What are my options here? Theyre claiming I didnt pay a bill from May. I never got a notice, nothing. I have never been late on my rent, never been late on my utilities. Assistant: Call them tomorrow a little after the office opens and ask them for more details about these charges. Once you have the details, you can decide whether you want to pay the amount because you owe it, gather information and show them proof that its already been paid so they can correct their ledger, or dispute the billing in the first place. You should certainly pay your current rent amount in full, by the due date, in person with a check or money order if the online system wont let you make a payment toward it.Human: No I think you misunderstood my post. They tacked on 889 extra to my rent as an Unpaid bill. I have not paid that, and have not been informed what the extra cost is. I cannot pay my rent until that bill is paid. Their system wont allow it.  <response>: Nope, I understood quite clearly. There are charges you dont understand, and you cannot pay your rent. Thats why I suggested calling your apartment manager to solve the first problem understanding the charges so you can take appropriate next steps and paying your rent another way to avoid being late. You say in the post that your rent is due on the 2nd. Take your payment to the office and do both at the same time.
