Banking

Dear Hellopeter, I have student achiever account with standard bank and i haven't deposited money into the account in 6 months or more to my surprise when i deposited they took - R 700 odds, I decided to visit the branches and called their help line number, below see the responses with no clarity. I have had the account since 2008 they have never took such money from me, now I need to know why... but they failed to give carity all my time going inside the banks & my airtime calling them no FEEDBACK.

1. They said I have an option of pay as you transact or monthly fee (that means all the years I was on pay as you transact now who changed it & why) 2. They say the bank has got bank fees ( why didn't they call me or let me know that my account is busy going up in the minus, I mean if I hand't deposited it means would see myself owing the bank millions)
