MZANSI4U DEBIT ORDER

I do not really understand how it happens that I get debited without authorisation. It is my first time experiencing such from ABSA. It has been 9 year using ABSA as my service provider all along I have been happy with the service, but now after this I will have to change my bank as I do not feel safe anymore banking with you.<br> I was debited the mount of R99. 99. It is the first time and I want my money back.
