I went on craigslist under pets ,someone was trying to sell a dog. They texted me back, an starting asking for a huge amount . I told them without thinking a little information. I told them i didnt have that kind of money. They kept texting asking very personal questions . I told them to stop texting me. They kept sending pics of a dog and textinghahahahaha. Told me they were not from here but would be soon. I was told i could not block them.What can i do? I. Am scared.
