Debit Order Chaos

When I signed up a New Contract with Vodacom during December last year, I was unable to get my Modem to connect. After receiving no assistance from the Customer Care, I wrote a review on Hellopeter. A consultant from Vodacom called me and explained the procedure to follow. This is what Customer Care should have done instead of insisting that I visit a store. There is no Vodacom Store close to me. Nevertheless, he adjusted my Account to compensate for the period that I was not connected. I further confirmed with the Consultant that when I signed up the Contract, I asked for the Debit Order to go through on the 7th of every month since my pension only gets paid into the bank account after the 4th and he confirmed that that is in order. However, this month I received a notification from the Bank that the Debit Order was due on the 1st and that it was rejected due to insufficient funds. After spending 2 days on the phone, going from Department to Department, I was unable to find out why the Debit Order date on their records showed the 1st whilst I specifically asked for the 7th. I insisted that they look up my Original Online Application, but no-one was able to do this nor would/could they access any of the calls that supposedly are recorded every time one makes a call. To top it all, I was told that now they are going to process TWO DEBIT ORDERS!!!!. I could not get anyone to explain this to me. The double Debit Orders went through my bank today. I also incurred unnecessary costs. So, the amount processed was R621.97 (R299.00+R299.00+R7.00+R3.50 = R608.50 -R621.97 = R13.47 no explanation charge !!!). I have a contract, but this now seems like PREPAID??? I request that either the person who assisted me before or another Senior person contact me urgently.
