Who called from 4434405129

I just got a call but they don't leave a message.  I do not answer calls that are not on my contact list unless it's a number I am expecting.  I don't have minutes to waste!!!!!!!

I've been getting calls from this number for almost 2 weeks now. Every time I answer they hang up. I return the call and it just rings. Who is this?

I just got a call from this number and before I could answer it or ignore it the phone froze up and it was like my phone was paralyzed.  None of the buttons worked.  I had to take the battery out of the phone and then when i put it back in and looked at the call log this call never even existed in my call log.  It freaks me out that someone is hacking into my phone or something.  Does anyone else have this happen to them???  Creepy!!!!!!!!!!!

when I called them back it sounded like she said rpm?

Stop calling me
