Run-around

I am really annoyed with the service I'm getting from Vodacom. I went to the Clearwater store and paid R1000.00 cash onto my account. When I received my statement today there is no trace of the payment I made. I phoned the call center and they are sending me from pillar to post to sort out their mess. I had to go back to the store and they now realized that the money was paid into someone's else account. I now had to pay and additional R1500.00 to sort out their mess because it's a negative reflection on my name.
