African Bank a total ******* with my savings

I opened a fixed savings account over 2 years ago and fixed the money for 2 years. Now that I want my money it turned out that the consultant that assisted me invested my money for 5 years without my consent. First she never reinvested my interest and now they expect me to pay R6000 to release my money of which the mistake was made by one of their workers. How the heck. I am also working in a financial institution and i know as a consultant you cant just do your own thing. I even received an sms stating that i have reached maturity but in the branch i saw abouy the R6000. I can never pay that. Its a *******. I need this sorted or i will take it to the media. *** is the reference i got to transfer my money. I went to the branch and the lady attemted to assist me but i was on the call waiting to speak to someone and could not wait so long because even the head office service sucks.
