Pathetic service

Does standard bank really care about their service provided to clients or only the money? The debited my account 4 months ago with 2 different amounts for 2 insurance policies of the same cover which I only agreed upon one and they still have not solved the issue and to make it worse December 2014 a female client of standard bank deposited money into my account by mistake and instead of the bank contacting me they gave me personal details to the client whom contacted my a few minutes later from outside a Branch in Cape Town, I was furious due to the fact that they gave her my details which is supposed to be confidential, I told the female that the person whom gave my details to het must contact me so that I can return the money, She then went to the Branch but some team leader or so contacted me and denied the fact that my details was given out and when I questioned it as I don't even know the person nor do I live in Cape Town, she put the phone down, Benoni Branch stated the will sort it out, almost one year after the incident and I still have no feedback. So how can I trust a bank like that???
