Business account blocked

Received 10k payment on the 23rd of April from my client as she always pays me monthly different amounts. To my surprised on the 30th when all other clients tried makeong payments money was reversed & they told me. Called Standard Bank they told my account is blocked cause of the transaction done on the 23rd bear in mind I received no communication from Standard Bank that my account is blocked 1st res flag. I submitted all documents needed no response. On Monday went to the branch they escalated the query Edward Mohajane is the one busy with the case no sense of urgency at all how did Standard Bank allow absa to flag my account as ***** but left their client that made payment to me account not blocked. Now Edward manager is involved Jabu in order to deal with the matter at hand she respond that my business doesn’t have a ncr certificate if that’s the case why did Standard Bank allow my business account to operate for so long without letting me know that I don’t meet the criteria? I don’t do money laundering or *****ulent activities this has affected me & my business emotionally & physically. Debit order not paid clients can’t receive service from me I REQUEST this matter to be solved in 24hrs account close money released o will use another bank
