I need help to get my saved up money

I fixed money with them but then when I went to the bank to put in a notice for the money to be withdrawn they told me the account was blocked due to *****ulent activities on the account. They put me on the phone to call the head office and was told to wait for 2 days for a call from them but nothing. Every time when I go to the branch it's the same procedure I even tried to talk to the branch manager it's like they don't care.
