Standard Bank

I recently had a problem with the functionality of one of the items on the Internet Banking Site which for three days was showing 'We have a technical problem, try again later'. I sent an email to the bank and received an email back requesting personal information to be sent back via email, which as we know is not a secure communication channel. I continually receive messages from Standard Bank to be cautious in disclosing information and yet this is what they ask me to supply: *Card number: *Confirm the expiry date on your card. *ID number: *Confirm any two beneficiaries on your account *Name any debit orders going off your account. Why couldn't they just attend to the problem I had raised with them and then send me a message that it had been sorted out!
