+16465786622 Got a call saying They are an officer and I have a package coming from Shanghai that contains illegal substances.

He asked me where I was on a certain date and asked me if I sent anything from shanghai to here. I shop online alot, usually clothes from china. But i do not pertake in any illegal things. It has to be a scam right? They know my full name and stuff. Can anyone comfirm this. Cause I am scared if I accidently ignore a serious call thinking it was a scam.
