The CSA are prolonging my payments on purpose

This May my boy is 20 years old yes ive been paying the csa for twenty bloody years at £61 and in the past £100 a week not forgetting arears of about £4000 which was not my fault.

What i cant work out is the csa are very quick to send me a payment scedule but they have not sent me comfimation of when it will end.

I have phoned them and all they say is oh we will get on to it striat away but have they no.

The only thing that worries me is as im in full time work the book keeper has to take it out of my wages untill further notice and she has not heard anything yet if you ask me they are just prolonging the situation on purpose im sure.

Can any body advise me what to do?
