late payment of accounts

O the 6th November I received a missed call from Vodacom, called back and gave all my information to someone. She was on # ********** 708. At 10.13am. She informed me I had not paid my account. I then inform her that the account was paid on the 3rd of this month. She then told me that on a different screen, it had been paid. I also told her that I normally paid the account about two weeks before the due date. She then told me my account is always late. I then stated to get a little upset with her, for her uncalled for bad attitude. As this was, I think, the first time, I've paid 3 days late. not great PR ,
