CSA cost me my home

I was giving my ex money then i started to see another woman and the ex found out and went to the csa but she then said i hadnt given her a thing even though the bank account in which i opened for her and the bonds i bought her were nothing.

Now with the help of the csa i no longer have a house and suffer from periods of depression. I had a son last year and was told by the csa that the child did not exist because we wanted to do a private agreement so we had to go through the csa, and yes its only taken them a year to make things so bitter between my sons mother and i that she will not let me see my son.

I’m always in work trying to make ends meet and all she has had of the csa is £1.94. Can some one tell me where all the money which is well over £200 a week going ??????
