Beware- sterling bank staff are fraudsters

The question is how did I come to the conclusion that they are fraudsters. The truth not everyone of them are but 90% of there staff are including their branch managers.
I Adiele Doris went to open an account with them on the 27th of August, and on the 30th of August my account was hacked, and the money in my account was removed through OTP meaning one time payment. I wrote a detailed letter to the branch manager that their account has been hacked. The case should be investigated. If OTP is one time payment who generated the other 3 codes that was used in removing the whole #50000 from my account if it was not one of your staff. Meanwhile the staff deceived me by acting like they work with BOI; - bank of industries. In giving out loans. My account officer came to snap my business premises as one of the requirement in accessing the loan. The staff also assured me that if I shared the without the Bvn no my account is save. I decided take my ATM card and withdraw my money the night before my money withdrew. They assured me no issues. I sent one code which is meant for one time payment but the staff generated the two other codes to removed the money between 11:45pm and 12:15am of August 30th. The branch manager told me that there is nothing that they can do about it and the staff denied that they did not deceive me. They all denied my visit and my complaints. I told the branch manager that I will tell the world that you guys are fraudsters. The guys said open account with any branch of sterling bank. So I concluded that it is not only in the branch I opened, there IT officers control all the branches and have a good knowledge of how to remove money from people account. Pls be warned!
