Non existing service from our business banker, Dawid de Jonge

We have two business accounts with Nedbank. Our business banker is Dawid de Jonge. He is the worst business banker I know, can not even say meet, because he is no where to be seen ever. We went to a branch to order a new card for the one business. He still has not linked the business to my husband's personal profile, so the short of it they cannot assist us. When they phoned him he was so rude and arrogant. Our businesses bring in a lot of revenue for Nedbank and this is how we are being treated. He emailed me a form to print and complete. The format is totally incorrect, unable to print. Tried to phone him and of course he is not picking up. I am considering moving our businesses to a bank that actually wants us as their customers.
