Change of email address

I had a Standardbank private account package which after being FICAed did not work out for me due to pathetic service. I moved my accounts but arranged for a debit order against my new bank to settle my Credit card. The bank had my correct FICA detail, including email and street address. Since switching the account I never received a single statement and just continued paying the DO. In August I requested that my statement be sent to my Gmail address. I noticed on the statement that my physical address was in Vanderbijlpark and I live in Mekbosstrand. So my bank statements went to some arbitrary person which in itself is shocking and I intend taking that up with the Ombudsman. I received one statement to the changed email address and then it all stopped again. I phoned today to find out what is going on and was told I cannot change the email address over the phone. However Standardbank took it upon themselves to change my email address to my ex employer email address. Come on man GIVE ME A BREAK!!
