Who called from 8136935824

Second call on as many days. No message=Spam.

they keep calling and not saying anything

You keep answering in any way and they will. Repeat calls from the same number with the same thing may be looking for times a live voice answers their calls. This will allow third parties to know when a good time to call is. Offering no kind of answer (if you're able) stymies that.

This caller asked for a person. I told them can I take a message. The caller hung up. How rude can people be..
