Blocking your account without notifying you

I have an account with ABSA this is the second time around my account has been frozen. First it was Fica purposes and now nobody can even tell me why. As their customer I should think that they should at least notify you of what and why they are doing what they do, because at the end of the day it is my money and not theirs. No assistance from the call centre you are constantly being sent from pillar to post and nobody even tries to assist you. This is ridiculous really, I cant access my own money and nobody can help me, this is by far the poorest service I have ever received in my life from Absa bank.
