Bad customer Service from Standard bank

<p>Called Standard bank to query my account that was in a negitive balance . My issue was that my banking app reflected different to what my statement reflected. Upon my conversation with a Olwethu Nogadla ( collections agent ) she was not helpfull at all. During some stage of thee conversation she also left me hanging whilst speaking to a colleague.i a I found this very disrespectful . She also said that that there was reference number of the call. I do not believe this . I would like a call regarding my issue !</p>
