Complaint Against a Service

Standard Bank South Africa / Unknown debit orders

I am Phumelephi Gumede ID [protected] have a cheque account from 1993, I have numerous unknown debit orders that are going through my account they are returned unpaid and am being penalized.

I have sent an e-mail to have them stopped, I was told that they have been stopped but I must contact them and cancel them.

My question is how do I call the companies that I don’t know?
How am I supposed to know their contact numbers?
Its second time I’m sending this complaint but no response.
