Unauthorized Debit Orders

It is with regret that one finds himself using this portal for these but I am sure that a lot of people are falling victim to the same,

I have an account that I use for household expenses, so I don't use it a lot. A few debit orders that I do not know of and have now heard and seen a lot of people complain about have gotten they way and through that account. The funny thing is that they are all just under R100. Just low enough so that I don't get a notification. Does FNB not have a proactive department that protects its clients from these kind of things?

Here are just a few I picked up,

01 Nov - VERIGONLTDIAFRICAMED ********** - R99.99 01 July - Hakeentrad9343ht110 ********** 30 - R99.00 01 Jun - Hakeentrad9343ht110 ********** 31 - R99.00 31 May - ********** 4831 - 99.00

You find one, you stop, reverse and cancel it and you're good for a month or two then another one comes along. I am starting to suspect that it could be one company that is responsible for this ****.
