Bad service

Very unhappy with FNB business department. How can u freeze my fnb business account without informing me. Then 2 days later want to send me this message. "FNB: Final reminder. Your business account ending ***x9234 will be frozen in 2 days for non-submission of your SARS CRS self-certification form. Please call us on *** urgently to avoid this situation. FNB a div of FRB Ltd Authorised FSP NCRCP2" You were supposed to inform me before putting a hold on my account and all the consultants I spoke to have no knowledge of whats going on. Everyone has a different turn around time and then I am being told i need this document or that document after I received a email stating that my account is compliant. This has put me at a huge disadvantage and I am not happy wirh the service received. I was told it will be sorted before 1pm today... Im still waiting. Please resolve this matter urgently or i am going to the Bank Ombudsman for lack of communication and for not notifying me.
