Fix or repair Daly

Haven at Charbonneau is an apartment rental businessThey charged me a bogus $late fee one monthI spoke with the property management person in the local office building and she said that it was a mistake and had been reversedThe charge has kept coming up over and over again and I have been told every time that it was a mistake and that they would reimburse me, but months later, I am still waiting on a reimbursement and they have stopped responding when I attempt to contact them
