Bad Service

I am Nomfundo Ntezo(Mimi).I have experienced a Bad Service at FNB.I have a case with them Case no *** against Nkosiyazi Hlongwa.He advertised himself in these social media as someone designing websites then He listed his prices and I became interested .I visit him to arrange about the business.He gave me His FNB account to deposit the money,I paid R1500 for deposit balance and promised me to do it within 2-4 days, 2 days after He requested the remaining R1500 balance weeks passed without completing the website claiming that Websites are expensive.I requested the refund because He can't do what he promised me to do.He refused and he ended up exiting the group we were discussing at.Now The FNB Consultant Kholiwe Ngwenya who is investigating my case is taking sides saying My money was withdrawn ,the one in the account is not mine.My question is withdrawn by whom?Who have access on the account except Nkosiyazi Hlongwa.She also mentioned that He designed the unfinished website according to the money we paid,In my understanding when you advertising something Customer will be attracted by the quality,Price of something you can't change when you are expected to deliver. We are all FNB Customers I understand She doesn't want to lose customers.Please I need my refund
