Debit orders and Salary switch not performed

App**** for a Prestige cheque account on 11/11/2015,was sent back to front. My account was only activated on 08/12/2015 after so many follow up. Dr orders some were switched others not,as for salary was never switched at all up to date.As the result those switched debited against overdraft facility against my will. Dinah reads open her mails from me and never responds. I escalated the issue to customer service centre and they referred it to the branch,subsequently Thsepo from the branch phoned me to ask for email trails to Dinah so that she can follow up, and I did send up to date I have not heard from her ever again. Seemingly nobody wants to own up the problem here. As the result I suffered financial loss and emotional trauma in this inconvenience. My credit record was compromised as well.
