Absa with unauthorized naedo vbainc debit order

Hi

I went to the bank today "absa" because i had a query about a very suspicious debit order of R99 done by NAEDO VBAINC , fami**** with that? OK!, Now look they are bouncing because there is no money in the account and that creates charges for me so i have to pay for that, Really? Do i have to? Same thing is happening to other clients a consultant told me that , how will i settle my overdraft when this is happening? I do not want to pay for those charges or give money away to total strangers i thought we safe here we could safely conduct transactions without any worries, in return this destroys my credit record.
