Creditors REporting negative info after BK??

[ka2sie]

My husband checked his 3 beurau credit report and transunion and experian only had a couple accts needing updating from our ch 7 bk 2 years ago this may. It was discharge closed sept/oct 2009. Anyways on equifax there were several accts showing charged off instead of ch 7 bk. One of those was BOA who updated it 04/2011 to show " charged off" We disputed that debt but were wondering since that acct was listed in our BK they cannot try to collect on it right since it was listed in our bk?? it seems that things we disputed and had corrected before with equifax dont end up getting changed. I know with BOA we forgot to dispute this one last time we looked at his credit report so this is the first dispute with them but anyone eles have trouble with equifax and disputes??
