Why did he do this

so I'm at the train station and a guy noticed me across the platform and came over to say hi. we traded numbers then told him I was on my way to my sister's house and that one of my goals this summer is to go to Coney island. so he told me he would get a $100 Luna card and would be glad to take me, but first has to go back to his house. I told him I wasnt going inside his house because I don't want funny business. so I went with him and he told me to wait at the train station by his house and wait for him till he comes back. I waited 2 hrs and still no sign of him, so then I called him and it rang then said something about text mate service not available. so I felt sad and went back home
