No service/assistance from Edcon!

I was notified by my bank that I have been blacklisted by Edgars / Edcon (not even Edgars themselves) when applying for finance. When I made contact with Edcon on Tuesday, they advised me that they cannot provide me with any information as I need to speak to the lawyers who is handling the account. When I asked for the lawyers details, I was again advised that they do not have the details, however they will notify the lawyers and they will make contact with me within 24 to 48 hours. I phoned Edcon yesterday afternoon to find out if I can speak to anyone who will be able to assist me urgently as the process is holding up my bank application. I was put on hold for 25 minutes and then the call was cut! I phoned back again and was put on hold for another 6 minutes as the call centre agent went to get her manager. The manager then told me that unfortunately they cannot assist as they are waiting for confirmation on the e-mail address (this is apparently their only means of contact with the lawyers) as the one they have no longer works. I find this very bizarre and ridiculous! All I want is statements of my account in order for me to verify the information as the account was paid up to my knowledge and to take the necessary action! How do they expect me to clear my name and account without the necessary information?????
