Business account department useless

I am extremely frustrated. I sent documentation through last week to the business department confirming my new company name and address, and asked for it to be changed on the system. I received confirmation this morning that this had been done. When I went to print the bank confirmation letter via online banking, the letter only states my new business name, and not the new address. I need confirmation for SARS (which I planned to go to tomorrow morning) to prove my new business name and operating address in order for SARS to do a bank account confirmation. I went it to the branch and waited 30 mins, and there were still 9 people ahead of me in the queue. I cannot take so much time out my business to wait for this. I called the call centre and spoke to about 8 different people to try resolve this until the last person hung up on me. What else should I do to get this confirmation letter? Please can someone get back to me who can actually help me.
