Fedup customer

I have been handed over to debt collectors from cellc in February 2022. Cell c never notified me that i was about to be handed over.

The debt collectors Brooks & Luyt contacted me in February to make payment. I made payment to them for the full amount owed in April 2022 and they provided me with a paid up letter.

I then sent cellc a email with the paid up letter on 14 July, as i saw my ITC record was not updated. I request them to update my ITC record as the contract still shows active and has a default, today is 3 August cellc advised that i owe them money and they cant remove the status. Once again the paid up letter was sent. I called in again and they advised that they cant send paid up letter. I told the agent i dont want a paid up letter because i already have one.I made him open the attachment to see. I just want them to allocate the payment and close the account.

How many times should one call for the info to be updated?
