Looks like old 'happyroach' is back up to his old antics... insult the hell out of someone and get his message ignored... even if there were a grain of truth in it.
So, let me try....
As I understand your post, you failed to pay your Dec 2000 on time and, when you tried to pay it, you included the 'late fee'. For some reason (not disclosed), the landlord refused this payment and delivered a 'notice to vacate'. You then took this as an 'eviction order', you vacated the apartment. So far, we have no problems.
Now, the issue becomes that at some point, a few weeks after your vacating the apartment, the landlord sent you a list of 'claimed' damages. You disputed the list (do you have the proof of receipt.... you did send it certified, didn't you?).
Here is what the Kentucky statutes say:
"383.580 - Security Deposits
A tenant who disputes the accuracy of the final damage listing given pursuant to subsection (3) of this section may bring an action in District Court. Tenant's claim shall be limited to those items from which the tenant specifically dissented in accordance with the provisions of subsection (3) of this section, or except as
otherwise provided, and if the tenant shall fail to sign the listing or specifically dissent in accordance with subsection (3) of this section, the tenant shall not be entitled to recover any damages under this section."

So, to answer your question, "What can i do?"
1) You can pay the amount claimed. (If you had handled this properly at the time, you might have been able to challenge this. But, since you didn't, you really have little recourse to challenge the claim. If you do decide to challenge it now, Kentucky statute requires that the landlord do specific things that, if violated, could help your case. Read the Act at the above link).
2) You can refuse to pay the amount claimed. The landlord could then sue you and get a judgment, allowing him the additional benefits of enforcing the judgment against you.
