Caller: 'DHL express'

Someone claimed they are representative of DHL (recorded message) called me regarding a parcel that unable to deliver to me. When I pressed the keyboard as instruction, a man picked the call and asked for my name. I gave them a random name and the man told me I have a parcel that they delivered to China and they found it has seven credit cards in it which will get me in trouble. When I said they can do whatever they want with 'my parcel', they hung up on me.
