DUPLICATED DEPOSIT CHARGED

I APP**** FOR A TELKOM LINE IN JULY 2015 AND WAS TOLD THAT I NEEDED TO PAY A DEPOSIT OF R700.00 BEFORE THE APPLICATION CAN BE COMPLETED! I RECEIVED MY STATEMENT YESTERDAY AND AGAIN I WAS CHARGED A DEPOSIT OF R1000.00! I CALLED YOUR BILLING DEPARTMENT AND THEY ARE NOT ABLE TO TELL ME WHY I WAS BILLED A SECOND DEPOSIT! PLEASE SORT YOUR BILLING OUT! <br> THIS IS A NEW ACCOUNT.... DON'T YOU DARE CUT MY LINE - I WANT THIS RESOLVED BEFORE I PAY THIS ACCOUNT!
