Is this incompetence or fraudulence?

I have been involved with the csa since 2001 although the parent of care has changed on occasions. My daughter is almost 19 years old and I have questioned if she is in full time education as she left school in 2011.

After requesting details of her education course in October 2013 I received notice I might add me contacting the agency that the claim ceased in august 2011. I add I have had no written correspondence from the csa, they informed me that they had 90 days to sought out the change of circumstances. Again I had to initiate contact via phone to be told that I was owed £6300. This was over the 90 day timescale however they said that I had to wait a further 6-12 weeks for the payment. I had been informed that the amount had been checked but it was a large amount and the secretary of state needed to authorise this payment.

I challenged this as it is my money also I want to know who is responsible either the competencey of the agency or a fraudulent claim. I requested compensation for my frozen pension with the local government pension of 6% of my wage for a period of 28months.Which would be in the value of £3000
