How to receive a short message of cosmetic plagiarism?

I wonder if it's a little late to answer now.

A few days ago, I got a call saying that I was also in the top 300, saying that I had samples. 128 Buy one get one free. I thought it was a lie, too, so I said no, just wanted samples. I borrowed a phone call yesterday and said that the courier had arrived. Today, I brought it to me. Yesterday, I was wondering whether I should take it or not, and whether there would be an extra charge. The courier called me today and asked me if I needed to pay. The courier said no, and then I went to get it. Haha ~ I really don't have to pay, and I don't need postage. This is only a small part. I don't know whether it is good or not. I just got it. I didn't open it. Try it.
