Vodacom non closure of settled account

I settled an account in August last year and when I check my Clearscore app it shows I am in arrears. I have contacted various agents on numerous occasions since 2022 and was told they did not submit my closure to Experian to update and it shows I am in arrears and that the account is still active and in arrears! I have requested them to update my information and apparently in February they did and yet it still shows an active and arrears account! I am so frustrated and angry by this disgusting service!
