Vodacom messing up my credit score

I have requested Vodacom to close my account after a ********** activity was done on it after I declined to upgrade in 2018 (Reference-EC-1JBD-2W2GJW handled by Roderique Lategan) . This was in April/May 2018. Last week I checked my credit report only to realize that Vodacom account is still active and shows that I am paying R1302 per month. How difficult was it for Vodacom to send the info to Credit Bureau that the account is settled? So today I called them and I am sent from pillar to post because I need my settlement letter with the correct settlement date on it and I need it urgently/ today. I am told to wait for 24 to 48HRS. This is my credit score that Vodacom is messing up and I do not understand how *********** a legal department can be. I need my Settlement letter urgently and my information updated on the Credit Bureau.
