HELP TO CLEAR

Hellopeter

I have a problem with a company trading as "Lifestyle Legal" they were always demanding money from me but when i ask them what service did i use from their company that need me to pay them i didn't get any answer for that, and they are good on calling and emailing like you owe them even thou you not owing them and they are rude , they end up listing my name on Default that's when i took action to pay the account but i didn't know what have i used that make me owe them, they gave a discount to pay R624.07 but i paid R630.00 due to that i paid at the ATM, they sent me CONFIRMATION OF SETTLEMENT LETTER with the wrong amount of R578.55 instead of R624.07, they have not cleared my name as Default AND that make sick, But if they can remove my name as Default i will be grateful.
