Wrongfully handed to ITC

My membership was terminated at the end of November 2019 , early April 2020 I received an Email from Bonitas stating that they will refund me an amount of R639.79. Late in April I received another Email saying I owe R1334.55. In June another Email was sent saying I owe R2155.76.

Our company pays 100% contribution, so I advised our HR to settle the amount, which they said they settled all monies owed to Bonitas for all employees that incurred after termination. To be safe I decided to call Bonitas and have them clear that amount/debt. The call center lady couldn’t give the full details about the money I currently owe. She then escalated to their finance department. A day later I received a call from the finance department where the lady confirmed that the company did settle the monies owed to them in April. SHE EVEN SENT ME AN E-MAIL(on the 15th of June) TO CONFIRM OUR DISCUSSION. I received another Email on the 23rd of June saying I still owe R2155.76 which I ignored because I have received confirmation that I don’t owe anything. Yesterday 26 August 2020 I received an SMS saying that I have been handed to ITC by Bonitas for the amount of R2155.76 I need my name removed from ITC for two reasons. 1 Bonitas’ finance department did investigate and find that there is no money owed to them (I will gladly forward the email with the query number if need be). 2 If there were still monies owed, Bonitas was supposed to contact my company as per their scheme payment agreement.
