Account paid in full

<p>I paid my account at a Pick n Pay store but still receive this message:</p> <p>Dear Customer, we have noticed that your Telkom Mobile account is overdue, which is due to non-payment or a payment being declined by your bank. Kindly make a payment within 48 hours to prevent the interruption of your service. Please call our call centre on 081 180 and quote reference ********** 74 with payment details.</p> <p>And I see on my statement I am charged for the unsuccessful debit. Since when is this charged for? I was never notified of this.</p> <p>Please assist</p>
