Debuting my account without my consent

Suddenly I realised I got a debit order of R99 from ROVING JETRJ676082, on the 15 January. I have no cooking clue who they are and where did they get my account details. And from all the other complaints it seems like they went on a spree to de***** everyone, I suspect some internal work with the banks. Mine was an FNB account, what's everyone else's bank, cause if it's only one bank that has the issue. The bank needs to answer. I'd suggest we all approach our banks, to explain how this was authorized. And who are these ****s
