Where did my warranty go?!?

I bought two X60 tablets in March of 2007 and ended up returning one soon after I purchased it (closed box return). I had also purchased an extended warranty for the one that I kept. Interestingly, that was assigned to the system that I had returned. Around March of this year I got an email saying that my warranty was expiring, when I contacted Lenovo and had them fix the issue (proof of fix in email). Apparently, it was fixed, when it really wasn't. About a week ago the battery went bad so I called for support when I was told again that I had no warranty on this system. They transferred me to the entitlement department, after explaining the whole thing to them, the person said that he would be calling me back. Two days pass, no reply, I call again, go through the same process again, then get told again that they would call back, three days pass, still no reply.

Today I called again, go through the same process once again, but this time I am told to resolve the problem through email. Now it has been more than a week since I first contacted IBM/Lenovo and I am getting really frustrated because on one really knows what to do.

This was my first Lenovo, and probably my last one. For the amount that I paid for the extended warranty I could have purchased two batteries and not had to deal with this frustration! Now I am wondering once hopefully someone fixes the warranty issue what other crap I will have to go through before my tablet will be useful again.
