For April, I decided to give a 10% discount to anyone who "likes" my Facebook page, and an additional 5% to anyone who shared the specific post where it was mentioned. The idea being to give benefits to the people who follow my page and also spread the word about my business.

I have a client who is ordering a painting, and I explained this to him prior to his ordering. He just emailed me saying he did both of those things, but when I log in to my Facebook management page, it says that no one new has "liked" my page or shared the post. All it seems he did is "like" the one post.

Is there a way to politely tell him that I don't believe he did what I asked correctly? Or should I just give him the discount?
