Who called from 8622312552

several calls to my cell . when I call back says the number is not in service .

I received a call from this number and did not get a message.  This number is unknown to me.  How do I stop unwanted calls?

Received a call from this number, did not pick up, no message left.  Another number from another scammer, it seems like.  If you can help it, never answer a call from a number you don't recognize.  They do stop calling, eventually... but new numbers will pop up.

I was called on my cell, when I called back on a landline it said the number reached is not in service
