Too much secrecy with my personal information

My account is in arrears and has been handed over outside debt collectors. I prefer to liaise with Standard Bank because the outside party doesn’t have a website or office contact numbers so I’m sceptical to deal with them. I just got off the fone with a standard bank consultant regarding my VAF account, he said he cannot give me the arrears balance and my installment amount.

Each time the repo rate goes up Standard Bank will not advise as to what the new debit amount will be, you just wait for them to debit it. I’m not happy that I cannot get information about my account
