Account still not closed/updaed after a month

I paid up my RCS account (balance paid on 20/08/15 in store & outstanding interest paid on 27/08/15 via eft) and I sent them proof of payment on 28/08. I followed up with telephone calls and further e-mails on 28/08/2015, 18/09/2015 and 22/09/2015 yet my account balance has still not been updated with the credit bureau. Each time I spent more than 30 minutes on the phone with call centre agents who say, it will take 48 hours but now I am absolutely fed up!!!<br> <br> When these entities want your business, they bend over backwards to assist yet now when I have paid all amounts due and need them to update my information, no one can assist. <br> <br> I am trying to buy a new vehicle and them not updating my account information is impacting negatively on this. <br> <br> Very disappointed indeed!
