I had recently chatted with someone on Snapchat chat area and they saved every single message and when we asked them to delete all my messages I had sent, they said no. How do I make all of those messages disappear? I tried going to the setting option where you can clear your conversations with people, but it wouldn't clear it. I also tried deleting her and blocking her, but all it did was make the chat history stay. It's really starting to bug me. Can you help me?
