Vodacom Falsely updates Credit Bureau when it pleases them.

After account was handed over I payed every month and eventually closed the account in December 2017. Vodacom still has not updated the Credit Bureau as it still shows the account as not updated and never reflected the times when I paid the account until December. When you call them regarding this issue they tell you to call their legal team that they handed me over to yet they falsely update my credit record and can't answer for that. Frustrated
