Who called from 3347153521

I too received a political text message from this number, (similar to 334-715-3518) the most recent one was sent at 11:30 PM. I called the number & kept pressing 0 & was able to at least leave a message including a request to be removed from their list.  Waking someone up late at night, can be very frightening.  How can we stop this sort of spam?

Received a text inviting me to initichat ? Pretending to be an aquaintance

Received a text from a Sara inviting me to intichat- said it was a friend?
