Double debit order a week apart

<p>So Telkom debits my account on the 3rd January 2017 for an amount of R917 and then yesterday the 9th January for another R917... this is the exact same amount for Decembers ADSL bill that has come off TWICE IN JANUARY?!?! Now Telkom I don't know what you think you are for debuting my account TWICE a week apart like someone that has a lot of money to waste. Tomorrow I will be in your canal walk store giving you guys a piece of my mind this is just ridiculous!!</p>
