Debiting my account after stating not to proceed w

So I apply for a loan at loanfinders SA. I realised its a waste of time as they just send silly emails instead of getting the process running. I call them up to advise them to withdraw my application as I will no longer need it. I received confirmation that it has been withdrawn and still I received an email thereafter stating that im liable to pay for their services I call them up again they advise me to ignore the email. Today they debit nearly R400 from my account after I've been told to ignore and after I wasted time calling them to advise them to withdraw! <br> <br> It's disgusting and it will be taken further!
