Begging them for a business account

I've spent 6 weeks trying to open two business accounts with FNB. The paperwork was sent through all in order but the accounts just don't get activated. I have spent hours on the phone and thrice got transferred back to the previous department that just transferred me to the current department. I have tens of emails where I send the documentation through, eventually begging them to stop sending generic emails requesting more information and just call me so that it can be resolved over the phone. yesterday it happened again and I am fed up. It is affecting my new business as monies are now running through my private accounts. Had FNB Business Banking been so professional as they claim, they would have known that mixing two revenue streams, private and business is not only poor practice, it is also dangerous and impossible to track and manage, let alone if SARS decides to investigate!
