Bad Bad Bad customer service

I requested a bond statement from the Nedbank call centre, and i was told my old work email address and cellphone number still reflect on the system in order to change it i need to got to the branch. i went to the branch spent almost 45 minutes waiting to be assisted, i gave my new cellphone number and email address and was told it has been changed. the branch could not assist me with the bond statement, was told to call the call centre again. when i called the call centre i am told my email address has not changed only the cellphone number that was changed. I cannot receive my statement as the call centre agent cannot change my email address or download the statement and send it to my new email address, i need to go to the branch again. this is very bad for customers, there are banks that are moving away from branches as we move to the digital world and nedbank is still in the stone age.
