Who called from 2021100910

this is the second time I've received a call from this number

I call them back

I've tried that once and it says the number isn't completed as dial?

I keep receiving calls from this number with only silence on the other end

It's only silence for me, but I saw another person post on a different site that a person asked for Tyler and when she said wrong number they threatened to rape her and do things to her mother... Be careful everyone. This world is crazy.
