Get onto your MP NOW. Also contact the adjudicator's office AND fill out an official complaint form. See a welfare rights adviser and get them involved, too.
They made a MESS out of our lives! We're £3000 in debt b/c of their repeated cock ups. Luckily, I didn't do business w/them by phone - all by Recorded or Special Delivery post, and I saved every single scrap of paper they ever sent us. So I had a case file inches thick to send to the MP.
Basically, they had my husband a) on Job Seeker's Allowance when he never has been in his life b) qualifying for disability element on his WTC when he was a SAHD at the time of application and therefore had NO employer. I applied for WTC and he for CTC b/c he was staying at home to look after DD.
We had to appeal. It took about 6 months before they wiped the slate clean.
By that time, we'd experienced EXTREME hardship b/c they cut us off when I was only earning about £13,000 gross/annum and supporting 3 people in the 3rd most expensive city in Britain. We had to borrow money, DH had to get a part-time job in the evenings/weekends b/c we could not afford outside childcare for DD, and I am pregnant.
I'm sorry to say, I want to spit every time I see Gordon Brown on telly. He's nothing but a robber baron to me and always will be.
