Lender Discharged w/C7 & Credit Report

My mortgage was discharged in my C7, even though I'd requested and signed (through the atty) my intent to reaffirm. The lender did not send the affirmation pkg as requested and I didn't know (at the time) one was required to be signed before the judge at the final hearing. I continued paying my mortgage. When I pulled a credit report, I noticed my mtg had been discharged - I disputed. I contacted the lender they said I was no longer financially obligated though they still held the lien. Now I find they're still pulling 'hard' credit reports. Why? If I am no longer financially responsible, no longer living in the home, why are they pulling credit reports? Are they allowed to do so?
