I wasn't given a discord nitro but I've never had one before

Hello, I ran into a problem like discord nitro for 3 months. 1 - I was not given a code by which I could activate nitro 2-my friend gave me this code and wrote to me THAT I HAD DISCORD NITRO, ALTHOUGH I DID NOT HAVE IT BEFORE! Please understand and give me discord nitro. In the mail it is not present, in the spam section, too, I looked at everything
