''Sick and tired of being sent from pillar to post''

I had a Morkels account which was handed over to Hammond Pole attorneys,I've settled the account in June already with Hammond Pole and I received my paid up letter from them but what's shocking is my credit record is not cleared because Morkels statements shows that I have balance which is owing & which I know nothing about as Hammond Pole gave me the settlement & I've settled the account the very same day I was given that amount. I've been sent from pillar to post by Morkels and Hammond pole .I can't even apply for credit because of them.I am so annoyed I don't see my self doing business with such people.
