THIS IS BLATANT THEFT!

Approximately a month ago I was looking for a loan and app****.<br> <br> I was contacted by someone shortly after that and asked to confirm some security details, one of those details was my bank account. I asked on the status on my loan and said that they needed to process my loan first.<br> <br> Today I see a debit order on my account went through with the following information: Ref HDLTRADIN HDLTRADING *** NAEDO DR 0<br> <br> I did not give them permission to debit my account and secondly I am still waiting to hear if the loan was either approved or declined.<br> <br> Is this not theft ? I have a good idea on going to the police station about this. Is there anyone that can assist with advise please?
