RECORDING button gone!

I have had so many technicians at my house but no one can figure out what happened to my Xfinity account. I have TV plus with 300 hours of recording on my DVR. But my DVR just disappeared and I cannot record anything on my television! It keeps saying I am not subscribed to DVR but it is part of my plan!!! Xfinity you need to figure this out. And it was the guy in the Philippines that destroyed my entire account! Why can’t you have in-house people in America?? This corporate greed has gone too far and nobody can fix my plan!
