This number tired to call me in July of 2021, but it never shows up in my call log, I only get a text message back saying I've missed the call and I can't text the number back. They called me again last night at 7pm (WA time) so it would have been 9pm (AEST) and I looked at the messages and noticed the texts are all at night. I dont know if I should call back or not?
