No communication or desire to rectify

I run a business and do numerous payments at the end of the month. Last night I transferred funds into my business cheque account to pay a number of creditors. The transfer was received no problem. I then tried to pay supliers and was not successful in getting the payments authorised and made. I tried again this morning and after failing again I spoke with technical support as the balance was adequate to do all the payments. They informed me my account was frozen and I needed to phone another department. After waiting for a long time I had the first call agent put the phone down on me. The second one I got through to told me it was frozen due to missign FICA documentation but she said this shouldn't be the case as I was never informed thereof. I have had this business account since 2002 and have never had an issue. She then said I will just have to wait until someone can resolve it but until then the account would remain frozen. I asked to speak to a supervisor and I was told this was not possible. I eventually got through to Candice who would investigate. I said to her, if I know what was required I could happily give it to them. It is still not resolved and I cannot bank or pay.
