fraud

I recently found out that someone is trying to use my account for fraud, I contacted my bank and they told me that on the 4th of april northway financial ltd tried to charge my account the sum arround ??120 , so I think that someone tried or did take out a loan with you on my name or my bank account. I would like to talk with someone from your team who deals with cases like this. How do I do that? thanks you.
