No assistance on blacklisting query.

I was blacklisted by a service provider and i paid them in full in March 2018 but they have not cleared the blacklisting. I have been trying to get a paid up letter since i made the full payment but i am not winning. I then reached out to clientele legal as i am a client seeking assistance but i was told to contact the law society, I told them that law society did not help. i was then told to send proof of payment to credit bureau, which they told me that they need paid up letter from lawyers. I am failing to understand what services clientele legal covers and why and why I am paying monthly premiums if i have to handle legal matters myself. this is very disappointing & shows lack of concern for clients by clientele legal.
