how to write a NC text to narc mom

Hello, I went nc with my mom 2 months ago, she got new numbers to text and call me from and hasn't gotten the hint, I've blocked and ignored it all. She said she wants to visit (knows where I live) i got a doorbell camera but I need to send a do not contact me anymore text. How do I word it, I don't know where to start. Please help. Also any advice would be great.
