Applied for a reconsideration to dd's DLA. Was previously getting mrc, lrm. She's been awarded hrc, lrm! I sent the form in 5 days late (due to severe problems we were having at the time with dd - school, mental health etc) so they've only backdated it to the day they received it, not the 6 weeks previous telephone call. Can I challenge this? Or is it just best left alone?
