Standard Bank online share trading take money but cannot provide authorisation

<p>I noticed recently that Standard Bank online share trading have been deducting a small amount, R70 a month, from my bank account. They have been doing so since 2010 (then it was less)! The small monthly amounts add up to a lot. I have terminated such authorisation as they enjoyed, and requested (i) proof of their authority to have deducted money, and (ii) a full recon. After more than two weeks, and repeated requests, it is clear that they cannot provide proof of authority, and will not provide a full recon. Yet they refuse to refund the sums they have taken from me - it seems, without any authority. They have never provided any service to me. I do not bank with Standard Bank, or invest through Standard Bank online share trading.</p>
