Listed Incorrectly - Financial implications

I used to have a BlueBean credit card about 8 or so years ago. some time around November 2015 I started getting SMSes threatening legal action if I didn't pay my outstanding amounts. I called the contact centre 3 or 4 times because despite the calls they were continuing to send me those smses. Each time they assured me that it was sorted out and account was closed. <br> Fact is I paid up the account and closed it many years ago. <br> I tried to change banks recently only to find out that I was listed by BlueBean and the bank refused to deal with me. <br> I have sent a number of emails to various people who are \dealing\" with the case but their responses have stopped. It was supposed to take 3-7 working days but it has been way longer now. I have a list of reference numbers but none of them ever get answered. I have tried to access credit to conduct business but this listing is causing me to loose income. <br> The worst part of all is that there is no one that you can talk to face to face and the empty promises on the phone keep coming. <br> I'd like this matter resolved so that I can go on about my business. I'd advise anyone else to be wary of dealings with this entity. "
