Yes, had trouble just like you. However, when I disputed that I owed them nothing (always sent in P60's so why problem????) received letters with fluctuating amounts due (�3600- �4,200???). Was referred to the local office where I explained all income & expenditure. On 2 occasions they have agrred that my income is not available to repay(???) any debt. Not once have they stopped my payments, unlike you. I think the system is mad. I assume that we both regularly update on any change of circumstance but their computers "Just say no"
There must be millions of us out there. It makes me angry!
