Who called from 4044003635

Don't know who it is or why they're calling

IN several hrs phone call 3 times. no massage, no voicemail  was left. so, i came here to try find some information.

I've Gotten 5 or 6 calls a day from these people! And if I ignore it they just call right back no voice mail either! It's harassment!! I'm on the do not call list but yet they still call me

Never answered. Received many calls in the past couple of days

It doesn't. I did it and 3 minutes later I got a call from the same exact number
