EDGARS account - Paid up letter request - Its like i never had an account!

I paid up my edgars account *** in 2014 and requested that the account. I contacted the call center and requested a letter that states the account is paid in full and closed and to this day i have not received this letter. I then phoned the call center and they are unable to pick up my ID number ***. The call center agent was able to see my account but had no access to it and transferred the call but the other department also could not help. I send an email to ***, ***, ***, *** which is all the available email addresses i could find online but for the past week i get read notifications that my emails are read by your departments and NO ONE responds, contacts me nothing!

I sent a message on your facebook page and received a response that they will assist and gave me a ***/GO.

ALL I WANT IS A LETTER STATING THAT MY ACCOUNT *** HAS BEEN PAID IN FULL AND IS CLOSED!!! is this so hard to do for a previous customer? I mean its like i never had an edgars account! I mean surely you keep records of previous clients?
