Driver gives stranger parcel then comes to stalk my house

My parcel was set to be delivered last week Tuesday. I got no call or anything just to find out 3 days later after Fnb send me an email asking me if I got delivery of my updated car license disc and I said no. They sent me proof of delivery and just to found out some stranger signed for my parcel. I attempted calling the company numerous times and they didn’t get back to me. The one consultant has the audacity to tel me I should just pay for it again and the driver who messed up with my parcel has been sitting in front of my house for 2 days now. How he is still employed baffles me completely. There has been all communication from my side and non from this business.
