Being harassed for non payment yet I have paid.

For the past few days I have been harassed by Vodacom for not paying my account. My account has been paid. I have even sent you the proof of payment because of the numerous public holidays. I have requested that you update your records to reflect the payment as it is not showing on my statement. Before you harass people about a non payment, maybe take into consideration that there has been a lot of public holidays and there might be a delay or maybe it is your offices who has not yet allocated the payments to the respective accounts. I always pay. My history with you will clearly show that.
