Pay back money debited without my authorisation

21/09 - Nolubabalo Sikwebu cold called me to sell me a max investment policy. I asked her to send me information and in our discussion mentioned I was instead interested in a tax free savings account for my daughter and nephew. <br> 22/09 - I sent her my children's details and my banking details for the debit order payment. <br> 25/09 - I sent an email to her:I accept the quotes for the kids, we can go ahead with just these two for now. She emailed back to ask if she must cancel max investment and I confirmed on email. <br> 27/09 I emailed her to ask her to confirm it was cancelled <br> 28/09 She emailed me requesting me to send a letter requesting cancellation which I immediately sent. <br> 1/10 She sent me email that the investment was cancelled. On the night of the 01/10 R3000 was debited from my account which I had not authorised. <br> It is now 04/11 and it has been back on forth between Nolubabalo and various call centre agents and I still have not received my R3000 back. <br> <br>
