Leopards Courier Scam

Leopards Courier Scam!
I got a call from a man claiming that he is outside my house to deliver a parcel under my name. As I was certain that I didn't order anything, I asked him about the company and he mentioned that he is illiterate and cannot read. That aroused suspicion in my mind. I told him that I have checked my cameras and I have sent the guard outside, but there is no one, so he instantly cut the call. The parcel was worth 1500. I think they are asking for less money so everyone will give it easily. One more thing, I also got a message from leopards courier official number about the courier from 'diamond hub' and when I checked online, there is no company by the name Diamond Hub in Pakistan. Leopards employees must be involved.
