I've been paying rent a center for over 1 year and a half now. For a 65 inch tv and a couch?

It's been over a month already and I haven't paid them or answered their calls. They have come to my house plenty of times. But I don't answer. My lease at my apt it's over in a month and a half. I already have another place in moving to. I want to know what could they really do to me, they just have my first and last name. I do not have a social security there for I don't want to keep paying them 3 times more of what the stuff it's worth for. Any suggestions?
