Should we pull away our business to another competitor?

So my partner and I app**** for a business bank account with Mercantile Bank a while ago. They asked for supporting documents, which were sent. after a week or two I received communication from Boitumelo Semakata, stated that they couldn't verify my identity(needless to say, I also have a bank account with their parent Bank Capitec Bank) I was advised to go to the nearest branch to get the verification done. It has been two weeks already I still dont know what is the status of the application. I then sent an e-mail on the 29th of June to Boitumelo and Londani Mutshembele( who was helping me from the onset) non of them rep****. Yesterday i sent a follow up e-mail, after tried to call the numbers on the e-mail signitures(pointless as they are not working) instead I get an auto-reply from Boitumelo that she is out of the office (no return date) and still no response from the two individuals. We're almost done with our setup facilities and we're literally held behind by the bank. I'm beginning to wonder if I should carry on using them as our primary bank
