Unauthorised debit orders!

Today I logged into my FNB online account and saw the following debit orders: Unitedrew R95 Legaleye R45 Rescue247 R45 Mediaassist R45

I NEVER AUTHORISED ANY OF THIS.

I didn't sign anything, was never informed or notified about any of these debit orders.

I never requested any service from them and would like to know who authorised and provided them with my banking details.

I tried looking up for their contact numbers to call them and request for a refund and for them to stop debuting my account and for my details to be removed from their systems with no luck.
