No Feedbank/response to e-mails

On 26 March 2015 I received an e-mail from Std Bank Internet Banking requesting me to amend the beneficiary reference on a recent internet Auto Share payment. transaction. As this payment was made via your Auto Share Invest platform, where I just simply select the shares I wish to invest in, I do not have the option of amending the beneficiary reference. On phoning your Internet Banking and your Customer Contact Centres, I was advised to forward the message so it could be investigated further. After no less than 9 e-mail messages to your Phishing Dept, Customer Contact Centre, Internet Banking and Information Departments, not one of my e-mails has been responded to, not even an acknowledgement!!! Is there anyone looking at customer's e-mail enquiries or are they simply ignored in the hope that they will go away? <br>
