They lost my account information

I have an active account with Edgar's since 2010, in mid 2010 I failed to pay my account due to uncontrollable situation, and my account went to errears. <br> Now early this year I went to Edgar's to pay my account because I have managed to recover. To my shock they inform me that my account and details are not on file, so I won't be able to pay them. <br> Now the problem is, when I went to apply for a loan it got declined, the reason is Edgar's, they told me I must go and pay my Edgar's account because it shows on my credit report as an account which is in errears. Now when I went back to Edgar's to pay them, they told me the same thing, that they can't find my details on file, which means I am not able to pay my account. And that means I can not get funding any where. Because Edgar's have lost my details but the problem is that it appears on my credit report as an open account in arrears, now i can not fix this because edgars has lost my details. Please Edcon help me with this, please find my account *** because all I want to do is to pay you the amount that I owe you. So that I can clear my credit record. <br> Thank you.
