Early Termination Fee

I signed up for Xfinity service six months ago when I lived in Clio. Michigan and recently moved to Ohio for a new job.  My new address is not in a Xfinity service area so I had to cancel service.  Now, I am being threatened with collections calls because I have not paid the early termination fee.  If there was Xfinity service in my new city (Cuyahoga Falls, OH) I would have stayed with Xfinity.  I also see that Xfinity is waiving all early termination fees to customers in Pennsylvania, due to Covid-19.  I guess Xfinity hasn't heard, Covid-19 hit Ohio and Michigan as well.  I don't even recall agreeing to, or signing a two year contract when I started service.
