Debited twice in one month by Telkom

<p>My Telkom debit is set to go off on the 1st of every month, seeing with all the public holidays my account was debited on the 3rd of January 2017, so why is it I get a notification that Telkom has debited my account again on the 9th of January 2017.</p> <p> </p> <p>Please reverse the payment and put back in my account.</p>
