Money deducted from my account

An amount of R4000 was deducted from my account without authorisation from me.<br> I have an open loan with FNB and an account that I recently opened with FNB.<br> To just deduct cash without talking to me or making an arrangement as I am aware I am behind with my loan repayments does not make sense at all.<br> When I enquired about I was told it happens, which I don't understand as they would need authorisation from me.<br> <br> Now I cannot pay rent or have transport money as I just started with a new employer and have the capacity to make an arrangement now.<br> <br> Regards<br> Yandiswa Dyantyi<br>
