I live in PA and my employer is appealing my approved unemployment claim. How is my position?

I worked for a company for 2 years. After this time I found another job that had steady hours and paid more than did my old one. I had steady and definite work before I quit my old job, which was one of the determining factors in the approval of my unemployment claim. I filed for unemployment when my hours started dwindling down to approximately two days a week. I have been receiving unemployment for approximately two months and I received a letter that my previous employer is appealing the decision based on his ertion that "work is available." He did this when I worked for him if someone would file for unemployment, he would offer them a menial job and if they didn't take it they're unemployment would end. I'm wondering if I'll need to accept it if I already have a job (that I'm sure will pick up) or if I don't they'll cancel my unemployment and make me pay it back. I don't think I did anything to warrant that kind of penalty, but what do I know?
