Who called from 3343219219

Received a call from this number at 2:38 pm. I have family in Alabama, so I thought it was a relative calling, but when I called back several times, the line was busy.

called and left no message:  I do not know anyone in Alabama

they called my cell phone and I did not hear it,  anyway,  They left no message.  I won't bother to call the number back as they never answer.

Received 2 calls on my cellphone in less than 1 minute, they didn't leave any voicemail messages  it's now blocked. It seems that the more I document these call on here the more I get. Anybody else experiencing this???
