Have I been scammed?

I just received a weird text message from someone asking to borrow my PS4. After I told them I purchased it at Best Buy, they then told me it was there's and someone sold it to Best Buy refurbished. They said they tracked me and we don't live far and they want it back. I've stopped responding after that because I don't want to give them any more information but what do I do?

Is this a scam and what should I do about this? I'm honestly unnerved. I've only had this PS4 for a week.
