CELLC LEGAL DEPARTMENT NOT UPDATING STATUS

I paid my one contract that fell behind due to the COVID-19 lockdown. I sent the proof of payment and they confirmed that my account is up to date - this was November. I went to upgrade my other contract but due to Cellc vetting department not updating my credit control status I have now been waiting since 18 December 2020 to upgrade. Cindy from Cellc Westgate tried calling CellC legal department and send them an email but with no luck. I paid the arrears amount as soon as I could, but now I have to wait months for them to update my credit score so I can upgrade.
