(720) 240 in Denver, CO

Someone called me from this number and breathed a hung up.

always calls telemarketer, no answer on call back , also same prefix plus 0213

This number just keep calling my phone. I don't answer it because i don't answer calls i don't recognize. I figure if it's that important, they'll leave a message. I googled the number and it's flagged as a telemarketer.

Never answered back after pickup.

hang up calls then when you call back it will not ring....

This number has called my phone periodically since December 2013. I received a call today 08.18.14. I'm not aware that I know anyone in Denver; however, in December 2013 my son vacationed there with friends. It is annoying, and I'm suspicious as to why they'r calling and why my number? Early on i answereed, and rceived dead air, hence forward, I ignore the call, and it registers as a missed call. No voicemail message is left.

Occasionally my phone will ring & this # comes up, but other times it doesn't even ring & I get an alert for a missed call from this # & now (720) 240-9740. When I tried calling back it didn't ring, there was only silence. There were 3 calls for me too. I missed the calls, was going to pick up the third time because 3 calls means there's an emergency. That's why I tried calling back- to see who it was and it was nobody. Just that silence with no ring... & then call just ends!

This number has called my cell phone a few times. It is a Denver Colorado number and I live about a thousand miles away in Indiana so I have no idea why they are calling unless they managed to get my job info. I work for a hospital in Aurora. Doesn't answer, just keeps calling and hanging up.
