Select Home Warranty Billed my account when I didn't live there anymore; denied I had an account. New Jersey

I checked my online bank system and noted that I was billed my monthly premium. The problem is...I sold the house and no longer live there. 

I contacted my credit union. They showed yhe billing. Prior to doing this, I had contacted the company twice. Both times they denied that I had a home warranty through them. All I wanted was one month refunded and my policy canceled. 

Now to get refunded...I need to do a dispute and have my card stopped/get a new card. This is a total pain but the only way I have a shot at getting refunded/not billed again.

I never used their "service" while in my last home. Now I'm not even there. I believe that is what you call FRAUD.
