There goes my money again

So last time I complained about me being billed for requesting proof of banking details by standard bank. The matter was resolved I received my R50 back only to be billed again for unknown transactions that took place on 5/12/2015 on a Sunday at Matlosana mall a branch I know for a fact is closed on a Sunday. And to top it off, the agent when assisted me when I called the call centre to query these charges could not explain to me what they are for. Standard bank I was not at Matlosana over the weekend. Please kindly notify me why I was charged. And please return my money.
