CSA threaten me with bailiffs

I have just received a letter from the c.s.a on the 4.06.09 informing me I had a child maintenance debt ( which firstly I wasn’t aware of)It was such a threatening letter about court,fines etc id had no previous contact from them even though they have my telephone number and address they stated that they would be evoking a deduction from earning order on the 15.06.09 from my workplace.

This letter never informed me of even the basic principles ie how much I was supposed to owe or from when, it took no account of my 2 kids situation as one has left school 2 years previous or the fact that my ex wife has been working full time for 4 years. When I rang to discuss this matter the guy ( I have his name) from the debt dept informed me I have arrears of £3600 and even though they were going to take £100 a month from my salary If I didn’t pay a lump sum of £2100 immediately they would take me to court and my possessions could be taken to pay of this debt I even offered to pay part of this amount £1000 now but this guy wasn’t interested he said he understood my position but that I had to pay the full £2100 NOW.

Im at my wits end I cant even afford to help my 18 yr old son Joe with his car ins ( which is £2000) Please can you help me.
