Deducting money off bank account without concent

I contacted Clientele call center to query how hospital plans work vs medical aids. On numerous occasions i emphasized that I did not want to sign up, as it was only a query. This was on 30 Jan 2016. On 02 March 2016, an amount other than what I was quoted, was deducted off my bank account without my consent. I queried with Clientele Compliance dept on 03 Mar 2016, and a promise was made to discipline the relevant party, and that Clientele would make a refund back into my account. The compliance department also confirmed that the person who signed me up did so without my consent. It is 11 days later, and the person in compliance, Makhezi, is not available to answer my calls, and reception refused to put me through to anyone else by the person who deals with my case. This was ********** activity on Clientele's side, and I am seriously considering contacting the FSB regarding this matter.
