Since you were over 18 and signed the lease, then you might be responsible - you really need to see a copy of what you signed.

You are lucky it is only on EQ.

You can send a DV to the CA - but then they might report to the other bureaus and then they might start actively collecting on it.  It might wake up a sleeping giant.

Until you know for a fact what you signed, and I'd definitely have the legal service at work take a gander, I don't think you will know what you are up against.
