Dispute and validate with 3 companies

I sent off validation letters to 3 companies I've been battling with over questionable items on my reports for quite some time. The letters were all received on the same day and the 30 deadline to respond to me expired on the 4th of this month. I am unsure what steps to take at this point. Do I send them another letter demanding it be removed immediately due to them not meeting the 30 day deadline? Is there a particular part of the FCRA I can quote to them demanding it now be removed from report seeing that they have not responded?
--------------------
might dispute the accounts right now by certified delivery mail
and see what happens
then follow the steps you talk of
-------------
i have disputed them all but they have come back as valid.
my next step was the validation letters which they did not reply to.
---------------------------
validation follow up something has to happen
if they validate the dispute
then one would think they would respond to a validation
