Tech support scam help?

Does anyone have a python or any other type of application that works in Kali Linux or windows that spoofs numbers and sends attacks to the number using the spoofed numbers.

I have a python application called advanced-flood.py and simple-flood.py. (LINKS BELOW) Can someone tell me how to use them maybe? or provide another application.
