Unauthorised debit orders .Scb -zfuneralz. on FNB Premium account

An unauthorised debit ordered has been going off on my FNB account since 26 November 2017. The initial amount was R99.99 and increased to R119.00 in June 2019. I assumed this was related to my previous company of employment but the debit orders have continued despite leaving the company. I am distressed as these debit orders were never authorised by myself and I was never made aware of the submission and/or creation of a new recipient.

The reference for these payments is .Scb -zfuneralz. - and, upon further investigation, it's become clear that this is part of a crime syndicate.

I have been able to dispute the debit orders up until March 2019, however, am unable to dispute prior to this. It's every month, over 2 years, and adds up to a significant amount.

This is very distressing.
