Y&G F2P review: Sent item I’ve not ordered and contains a razor blade.

I received a parcel with the wrong name at my address. I check with neighbours and no-one of that name lived locally. The parcel had a customs label on it but a UK return address which I thought was strange. I then read the customs declaration a bit more carefully and it said utility knife. I didn’t feel comfortable sending a knife in the post so decided to open and it’s a strange plastic paw shape with a button at the back which extends a razor blade out the top of it! I’ve now googled the company and see there’s lots of complaints against them. Not sure what to do now.
