Scam for a SIM card, be careful and note down that number. Mero

Hello, someone tried to scam me. They made a simple transaction of 20,000 from a number that I don't have in my contacts (86848624). They called me saying they had made a mistake and asked me to return the money, but I told them I'm very sorry, but I can't. She is from Santa Cruz, Guanacaste, and has only one number. She told me her name was Carolina, but on WhatsApp she has another name, Daniela. When I mentioned that I had spoken with my lawyer because she insulted me and I am a disabled person, in the end, she said to keep the 20,000, she was giving it to me. Before all this, she told me a bunch of lies: that she had 5 children, that her husband was unemployed, and that she had to pawn her tools because there was nothing to eat. I apologize for the long message, but I want you to be well informed. Thank you.
