VODACOM account issues

I have signed up for a new contract on an EXISTING Vodacom number that I have changed from contract to pre-paid previously. The SAME number was used to sign up for a contract again. The sales consultant erroneously swopped the last two digits, and the pro-rata rate of R 196.00 was deducted from my account. A few days later, we determined that an error occured, and the wrong cell number was activated. The whole thing was reversed, however, the R 196 that was deducted for the pro-rata invoice was not paid back to my Standard Bank account.<br> My debit order runs on the 25th of each month. Yesterday, 24/03/2015, my Standard bank account was debited AGAIN for R 203 (which is the full premium of the new contract). The reason, as per the Vodacom agent, was that all new contracts are invoiced within 30 days of activation.<br> When I told him that I have ALREADY paid the pro-rata invoice of R 196 upon activation, he claimed that the R 196 was credited back to my VODACOM ACCOUNT - which is NOT the Standard Bank account where the funds were taken from.<br> The debit order was unpaid, due to insufficient funds, and I now have to pay R 115 for debit order reversal fees. This is UNACCEPTABLE.
