I feel deceived!

I've had the cat accident plan for 2.5 years with no claims. I submitted my first claim for a bite wound abscess, just to be told that it wasn't covered. It clearly states on the website that abscesses are covered under the accident plan, but I was informed that the plan on the website is the NEW accident plan. I have the OLD accident plan and its not covered on that. I feel deceived and I'm canceling immediately. I just wish I'd read more reviews before I chose this company.
