Unfair labour practice

In January and February I was taxed over by about R2000 for each month totaling almost R4000 every time I went to the district office to enquire I was taken from pilar to post. I was also told to wait for the financial season in April and now I'm told the money I'm enquiring about is from a previous financial season and the is nothing they can do. My problem is if I get a lawyer I will probably be charged the amount I'm trying to get from the department. Please I need help in resolving the matter.
