Unauthorised debits of R99.00

Hi Nedbank,<br> <br> I am a very concerned customer. I have recently noticed that I am having a debit order of R99.00 in my account from a MZANSI4U. I have no cooking clue who this is and I certainly have no dealings with them. I then got another debit order for the same amount and this time, the reference number is some weird long number.<br> <br> This is not only weird but unacceptable and I need the money refunded to me as a matter of urgency<br> <br> Regards,<br> Xolisa
