Account Status not updated on Credit Bereau

My Vodacom fibre account is up to date however it reflects as in arrears on Experian and has since been affecting my score. There is an amount of R220 some odd outstanding. Vodacom has since debited my account for that amount and account is up to date but Vodacom has not updated this account and sent the updated information to Experian. Their call Centre keeps promising to send the updated information to Experian and month after month the account is still in arrears.
