UNFAIR BLACKLISTING

I am very unhappy and frustrated with the way edgars is handling my case. On 02/03/2017 paid off my edgars account and i received a paid up letter. few months down the line i was blacklisted for non payment on transunion and experian and they used this account number ********** ********** 02746 which does not belong to me. My account is ********** ********** 74663. upon investigating it was confirmed that this account belongs to another edgars account customer not mine but we share same date of birth. since last year i have been trying to get the listing removed to no avail. if i call the call centre i am informed that my account is paid off and there is nothing they can do. experian is refusing to delist me because they said i am owing edgars. i am being sent from pillar to post with no joy at all. i tried to apply for a mortgage bond and i was declined because i am owing edgars. This is a total mess up. PLEASE CAN SOMEONE FROM EDGARS WITH BRAINS ASSIST ME HERE BY REMOVING THIS UNFAIR BLACKLISTING BECAUSE I OWE YOU NOTHING.
