App not working since January 2015

During December there was an attempt of ***** on my Credit card and the Bank cancelled my card and issued a replacement. Since January I was not able to use my Banking and Online Trading App. After numerous e mails via the website and no reply, I logged a call with the Call Centre with ref ***. I received an sms that the call will be dealt with by 25 March. Nothing happened and I called again with no reply. An e mail was then send to the Complaint Resolution Centre with ref ***. They responded with an e mail stating that I must allow until 10 April 2015 for resolution. Nothing happened. I called again on 14 April 2014. After an hour on the line and yet another ref *** and confirmation that I will be called back, still no reply. I am a client of Standard Bank my whole life and always defended this Bank but now understand why estate attorneys called Standard Bank to be the worst institution to communicate with - CLOSE YOUR CALL CENTRE AND TECHNICAL DEPT, it is worth nothing. Please remove the e mail address on your website, it is also worth nothing! STOP your App, as it is not working.
