Unknown Ammount Charged

<p>A short while ago there was a problem when they debited the incorrect bank account, and the debit order bounced. Thier help desk sorted out the problem and passed a credit note for the amount, as the error was from one of thier shops. So far so good</p> <p> </p> <p>Today I started to get sms saying that there was an outstanding amount of R31.54 which is not possible if the credit note was correctly passed and the previous month went through on the old bank account.</p> <p> </p> <p>Please call me to sort this out</p> <p>Thank you</p>
