Four different google recruiters reached out to me and all four of them ghosted me.

I was so happy when they reached out to me for the first time. I went and replied and then I waited and waited. Then same thing happened over and over. With two to three months gap, these people reached out and once I replied they ghosted me and few of them didn't even see my message. It was left unseen. I followed up with one recruiter. He said the first guy is holding yours and he will get back to me. What the hell just happened? Till date I am still waiting.
