Disputed an innacurate account one deleted two did not, now

I have disputed with Equifax my name being listed on a loan for which I did not sign. I was on the associated checking account therefore listed as a co borrower but was added to the checking and loan well after both were opened. That being said, Equifax has removed the item from my credit report. I then disputed with TransUnion and Experian online and received a confirmation that the account was correct. I now realize that the options given to dispute an account were to broad and did not fit my situation. I then mailed a copy of the Equifax decision and a detailed dispute to both credit bureaus and have not heard a thing back from either, its been over a month. I also have requested from the creditor a signed copy of the loan documents proving my responsibility and have heard nothing from them either. Now what?
