My cheque account is frozen

My cheque account has been frozen by FNB. On 10 May 2015 I went FNB Brakpan to find out the reason. I was attended by Clara van Schalkwyk who told me my account was frozen/ put on hold due to inactivity, the last deposit was on 28 April 2015 its just a month. She called Ramsey who she said is the only person who can fix my account, she was not available. She said I must come back later. She then gave me Ramsey's no to call her. I went to the branch hoping FNB will help me to access money in my account but i was turned away. This not the service I expected from a big financial institution like FNB. I still cannot access my funds.
