Ghosted and forgetten

I have been so deeply deeply frustrated with the business banking application process with Mercantile Bank. After doing much research and asking for recommendations, we were told that they were the best. We started our application on 2 August 2022 just after registering our company on the CIPC portal and promptly received a phone call. The process was smooth until the docusign wouldn't work. After some troubleshooting the rep dealing with our case seemed to give up and stopped responding. After some time I called their main lines again to either pick up the process or restart it - got a call from an agent and he pulled up our info and seemed extremely competent, until he also proceeded to ghost us after completing the docusign details. We have signed all documents, forms etc and received confirmation thereof but have received no information on our actual bank account, haven't received our cards, haven't received a call nothing. It is now 7 months down the line and we do not even know if we have a bank account or not!! We shouldn't have to beg to set up our business bank account, it's ridiculous.
