<prompt> Human: Long story short, I tried to pay my rent online in Oct. 1. Plenty of funds were in the account and my bank has no minimum requirements for my checking account. The rent payment goes through online. I check a few days later and the rent hits my account on Oct. 3rd. Almost immediately on Oct. 3rd the funds are returned to my account. I go into the leasing office and they double check my account. Nope, all is good, the payment posted. I explained what happened and they literally said all is good, and even if something happened, on their end there is nothing they can do. I go over their head to corporate and repeatedly call about the problem. Even up at the corporate level they claimed that their accounting was still OK and that I made the payment. I call the bank and they basically said that the payment never went through. I now have an extra 1800 sitting in the bank for no reason. I mean I know it is tempting to not say anything and try to keep it, but I know Im going to get fucked over somewhere along the way later, either by the landlord who comes back 10 months later and tries to charge late fees, or by the bank who is going to take it back out of the blue when Im not expecting it and I overcharge, or theyll try to charge me fees for something. I can just feel it. What should I so since no one is owning up to bad accounting?  <response>: Wait for a couple of months; chances are the landlord will find the error on the next month.Id recommend you go into the office and get a written confirmation from them that they have received the payment; that way, if they come back with a late charge, you have proof that you checked and were told it was done.As long as you stay there - assume its their money, dont pull it out of the account or use it. If you are moving out - after that, close the account, and move on..
