Unprfessional and No Security Measures

Major Issues with setting up a simple debit order. I have emailed more than 5 times, and attempted to speak to someone for over a week, in order to confirm the reinstatement of a simple monthly debit order. I now received a call from someone who wants my bank card number and security code over the phone. If you think I'm just going to give that to a random caller YOU ARE INSANE! This system is very unprofessional and security measures are atrocious. Get your system up to date with the modern world already!
