Pathetic service

So today my ABSA card was going to be delivered at my workplace and when the courier guy arrived , i had my id (the one i used to apply for the card) and my temporary id as i am now a Mrs. The guy requested a marriage certificate and then when i went to the reception to give him. He advised that he is not allowed to use a temp id and i cannot use the id i used to apply for my card. What exactly is the problem?. I am now married and my surname has changed and i only app**** for temporary id as i am waiting for my ID. According to ABSA my temp ID is INVALID.
