Value Added Service Fees

I have already sent an email to FNB a few days ago, have yet to receive a reply. Have also queried my bank statement. Can they please explain what is Value Added Service Fees. Last month this 'fee' cost R222 and this month its R155. I already have an account fee (R105) and i pay bank charges and fees on almost every transaction AS WELL AS a Service Fee which is taken from my account monthly. I would like an explanation and breakdown of Value Added Service Fees because I really doubt that if I am paying for everything on my account, how can there still be extra charges. I'm very annoyed because this means that collectively, all my charges on my bank account could amount to around R300-R400 per month, which was not sold to me when i opened this account - i was informed of one amount per month.

Can FNB please get back to me on here if its too much trouble to reply to my email or call me.
