Will not provide PAID UP letter

After settling 2 accounts of almost R20,000 I still after one week cannot reach accounts for a paid up letter I reported them to NCR but that takes 15 working days. Consumers have the right to share this letter to update at the credit bureau but this business is so inaccessible and unprofessional they want to keep you a client for life with the POOREST SERVICE EVER - STAY AWAY!
