Lying to a client with a Straight Face

I went to my local branch to have a small issue resolved . however the experience and information received was disappointing to say the least . 2 days later I had double the amount charged from my account and upon calling the call centre the truth came out and the agent at the branch **** to me but nothing can be done apparently to fix the issue ... makes me now question the integrity and honesty of my bank ...... how must I trust you with my funds if I cannot trust you to give me Correct information ....Capitec is becoming like the other Banks in SA - They don't care about the client only their Money .....
