<prompt> Human: Hello everyone.So this week my partner accidentally paid our rent 925 to her old landlord. A silly mistake, but it was in her saved payments on her online banking, and these things happen.We have contacted the old landlord a property management company who have said they will sent the money back, but will charge 10 for doing so. She lived there well over a year ago, there was no outstanding rent and no unsettled damage or anything like that.We need the money back ASAP, as our current landlord is busting us to pay the rent ASAP even though weve explained the situation and are doing everything in our power to sort it out. Even though its only 10, im pretty annoyed about it, because I dont know what right they have to take 10 off of us, just because we accidentally sent them some money. I m pretty sure that if they somehow accidentally sent us money, we would have no right to keep any of it! nor would we expect to.So once the money gets sent back to us, I was planning to phone them up and argue with them until they send the money back its not just a matter of principal, times are tight!. What im wondering, do they, legally, have any right to retain any of our money from an accidental payment? Obviously, I have no intention of taking them to court or anything, but before if I phone them Id like to know if im in the right or not? Is there anything else I should know, or have prepared before talking to them?Thanks!  <response>: There is a cost associated with processing your refund. From your perspective you dont see any cost but imaging someone has to spend 20 minutes filling out out some paperwork and then processing the actual refund or mailing a check, cost of postage, etc. Business accounts often charge their customers based on the amount of transactions on the account.While I dont suspect the cost would be 10 then again, the measurable cost could be more, you can definitely say that the cost is more than 0.My advice, take this as a cheap learning experience.
