They called me few times on my mobile asking me to pay the debt or they will send the debt collectors to my place . I luckily found the landlord of that property . He sent me a signed letter clearly writing my stay period in that property . I sent that letter to Buchanan after their next call of harrasment .

Question: What could have happened if they had n't gotten the form with a signature ?
Answer: None of the above choices .I could have avoided further investigation .I could have denied the wrongdoing .The aggressive calls could have continued .
