I recently moved out of my apartment, I gave the keys to the landlord on the 14th of June. I advised the landlord to contact me with any amounts that I might owe for the 14 days. Well, I did receive a notification just not the one I expected. I received a notice in the mail that I had been sent to a collection agency for 601 dollars. No one called to say hey this is what you owe they just sent me to this agency 11 days after I moved out. This could ruin my credit what can I do. Is there a due process of law for landlords on this issue.
