Just freezes my Flexi reserve account without any notice

They just decided to freeze my account without any notice, when I phoned in on the 1st of November, they told me that they need proof that my property is insured, why I don't know as I am fully paid up on my bond and the house belongs to me, not to them., but in any case I have done that and send them the proof they wanted, and still now I cant access any of my funds in my flexi reserve account. Today I went in to the Branch thinking they would get this sorted out, NO, they cant help me I must call in, waited for half an hour on the line to get it answered, and just get told that I will receive a email, worst service ever and still I cant get to my funds
