Credit Record Update

I was overdue on my Vodacom account, however I paid the account in full to clear my name with Vodacom and get my account up to date. But I had to contact Vodacom multiple times to fix my Credit Record in which they did, but every time it was wrong then my account shows it is up to date then a few days later I am in arrears. Now it is stating yet again I am in arrears, I am very confused and not receiving the correct and clear answers.

1. I am not in arrears 2. I paid my account so please just update my credit record accordingly 3. I cannot make any credit because of this wrong statement on my credit record
