Poor service

I went into a branch @ st George in Cape Town to withdraw from my investment account. And was given a quing slip. After going through the slip I saw they require a bank statement to possess the withdrawal. Rushed to get my phone so I can send the statement from the banking app. The lady who was assisting me asked for the statement and I asked if she can provide me with her email so I can send the requested document from the Banking App. She said it was against the company rules. Which is a pathetic in the day of technology I must go to a bank and get a hard copy statement? You staff is rude and if that's the company rule it belongs to the stone age.
