OT.Any Knology ISP Users here?

I use Knology as my ISP, I download newsgroups with Outlook Express and tested Thunderbird with the same result. The problem I'm having is, threads are losing their posts. A thread may have ten posts and then the next time I check, it might only have five or could have completely disappeared. I have contacted Knology, the first hurdle is to find a rep that knows what a newsgroup is. I finally found someone aware of the problem, although they can't give me more info. I have also contacted Usenetserver, my understanding is they provide newsgroups to Knology. Usenetserver admits they have a software problem causing my complaint, but it seems to be about two months that I've been losing posts. How long should it take to fix a problem that is the core of your business. I guess that's my rant, just want to make sure others are having the same problem. Anyone? Is the a free service to get newsgroups? Mike
