Very Rude Business Banker

For no valid reason and without any phone call or email, Bidvest Bank suspended my business account after l received a payment from a client on the ***.I have a sent them the proof of payment from the client and all the related documents. My client is expecting me to start on the project they paid for as it is a construction project and has timelines ,but l cannot because they do not want to unsuspend my account so l can start working. They are giving me a turn around time of 14 to 30 days.The worst thing is that my designated business banker ,Busisiwe Ngwenya, whom l have been communicating with about this matter and who is supposed to understand my needs,told me this morning that "ngiyeke ukumbangela umsindo"..."I must stop making noise for her" because she's not the one dealing with the matter .I must just wait for the 14 to 30 days despite that l have pressure from my client to get the project started. How do you train your stuff to speak your clients Bidvest Bank? Do you even recruit the correct skills or you just pick up anyone willingly? Do you care that I'm bound to lose clients because of your actions? What then is the purpose of you allowing me to open a business account when in actual fact l cannot run that business using your products?
