Paying On Debt w No Results

Me and my husband have been consistently trying to get his credit str8. We've been paying on his student loans for the last 7mnths consistently... its gets drafted out of his account automatically...well we've recently found out tht the pymnts r reported late each mnth.... The excuse tht we're given frm the collection agency is tht its not up to them to report to bureau its up to the student loan company tht the loan was originated through...We called them and they said it wont become current until its caught up? I dont know wht the caught up point is I didnt speak to them my husband did. We original went in asking for a rehab on his loan but the collection agency said they dont have one!? This seems really bizarre to me seeing as how once I started paying on my defaulted loan the payments automatically became current and built my credit off of a rehab no questions asked by me except to say i want to rehab the loan. Now though we are paying on the loans his credits at a stand still which is nt helping us at all... We're trying to get a house Im prego and due in three months and dont know how we'll ever break the barrier on his credit if they continue to report it late...
