They chasing something I never received bills for. Can give full details if wanted (they're really boring!) but am 85% sure I'm right. The debt agency's fee is an extra £200 which I really could do with not having to pay at the moment.
Has anyone challenged a debt agency before and won? How nasty do they get? Trying to gauge if it's worth the potential agro as am scared of going to court but also really annoyed that this has happened!!
