Fnb business account handed over to legal

So I recently received a sms in March Stating my business account has been handed over to legal sdk attorneys and ref was given . This sms was sent to me from sdk attorneys

Fnb has not given me any notice that i owe any money , so how is it my account was handed over without communication.

Email was sent to sdk attorney and still no feedback As we know January and February are less income months for self employed individuals why was I not contacted by fnb .and how do I resolve this ????

Fnb I was comment that the lack of communication is pathetic.
