*****ulent Credit Enquiry

I have a problem with a *****ulent credit enquiry that was done by FNB without my knowledge and consent.I was opening an easy account a normal account online and I was advised a consultant would call the following day to complete the process.I was called the following and we completed the process of opening an easy account.I know nothing about a credit enquiry and I did not ask for one.I have contacted FNB several times to have this removed but no one is helping.I have been trying to contact FNB customer care and complaints but the same people keep explaining that they do credit enquiries automatically when opening accounts for clients but they are not saying anything about having this removed as it was done without my knowledge and consent.
