try to keep calm as you have got a long time to go till it all gets sorted out. they (DWP) try to grind you down to make you give in ond pay wot ever they want back. i was in a situation like yours. i had my first interview in january 06 and denied all allegations as i was inocent. my second interview was in march 06. my benefits had stopped, i was bringing 5 kids up on my own feeding them toast every day as couldnt even aford to shop for food. i had to sell anything i had worth owt. iwas told my case was with a decision maker and they would let me know when the decision was made. i heard nothing,each time i phoned no decision made yet. the next thing was a dept letter for 50,000. i appealed and waited for a tribunal it took months and all the time constant dept letters demanding 50,000 every week and phone calls demanding payment! then tribunal had to wait for court date. so i went to magistrates court, then had to wait for crown court. all the time getting dept letters. council tax started sending bailiffs demanding 2000 they were very abusive and threatening. i eventually went to court inMARCH 2008 two year after my second interview!! i stood on trial for 5 days with a judge and jury. was being charged with 5 counts of benefit fraud but it got split into 12 counts during the trial. at the end i was found guilty of count 12 only and not guilty of other 11. the judge said the over payment will now be 3000. if i had been found guilty of all counts iwould have gone straight to prison for two year. i new i was inocent thats why i kept fighting. but it didnt stop dept letters they still wanted 50,000. i had to fight a tribunal that happend in augast 08 and i won that aswell and i am still now fighting to get the 50,000 down to 3000 like the judge and the tribunal said but the DWPthink there above everybody, i cant believe they get away with it but they do.
