Debited amount not reflecting

I paid an amount of R469 in advance when I took up the contract for a new phone and was told that the amount will be debited from my bank account before I receive the phone. The amount was deducted before I got the phone but when I received my first invoice, the amount that I paid doesn't reflect. I emphatically asked the lady that assisted me over the phone to take the contract that when will the amount reflect on my account and she said first invoice. When I inquired, I was told it will only reflect on the 3rd invoice. Why did consultant lie to me that the amount will appear as my advance payment in my first invoice. I called and indicated that Telkom should listen to the tape of the discussions I had with the consultant and I requested for a copy of the audio but nothing has been received by me. You guys should be serious and stop this poor services
