CSA taking money when I have a private arrangement

I recieved a letter 3wks ago saying £6:50 a wk was gettin took out of my money when me & my mother have a private agreement as they live next door.

I bought horses for my daughter, which is a ongoing expense. She gets games wily nily, christmas, birthdays. I could go on.

Anyway I rang the csa who told me my mother had to ring & cancell the case witch she tried, & i say tried to. They gave us another phone no, they didnt have us on file so we rang first no again, then they started talking about my brother who is 24. Then they said it was somebody else who was paying that was the childs grandfather, not the father.

Do the csa no what the hell they are doing? They should scrap the old way as ive been paying for a year but nobody told me &i never relised till now $ cant claim back.

THE CHARLETANS anybody agree?
