Default listed for paid up account

I made an arrangement to settle my Finchoice account which I did. I then got an sms from Transunion of a default listed on my profile and when I checked it was for that account. The whatsapp agent while they take a while to answer was very helpful and directed me to contact a call centre. I did that and I don't know who I spoke to because they just said Hello. I provided my details and they said the balance is R0.00, when I asked for a paid up letter as on the site there is just a JPG not specifying which account is paid up. I requested a paid up letter and the agent said I must wait 7 days and someone will call me back. When I wanted to ask follow up questions they repeated someone will call me back. I still habe not had a call back. Please could I get assistance here as I have to apply for rental and the credit score is all the way down with a default listed and no paid up letter. I essentially just need the paid up letter in PDF format please
